Question 1Understanding Music
A piece is marked at a tempo of 60 beats per minute. How long does each beat last?
- Half a second
- One second Correct answer.
- Two seconds
- One minute
Explanation
Tempo in beats per minute states how many beats occur in one minute. Dividing sixty seconds by sixty beats gives exactly one second per beat, so each beat is one second long.
Question 2Understanding Music
In a major key, which scale degree is a semitone below the tonic?
- The leading note Correct answer.
- The supertonic
- The subdominant
- The mediant
Explanation
The seventh degree of a major scale lies a semitone beneath the tonic and is called the leading note because it pulls strongly upward to resolve. The subdominant, mediant and supertonic all sit further from the tonic.
Question 3Understanding Music
A time signature of 6/8 is best described as which type of metre?
- Compound duple Correct answer.
- Simple triple
- Compound quadruple
- Simple quadruple
Explanation
In 6/8 the six quaver beats group into two main pulses of three, so the music has two dotted-crotchet beats per bar. Because each main beat divides into three, the metre is compound duple rather than simple.
Question 4Understanding Music
Which instrument family is defined by sound being produced from a vibrating string?
- Membranophones
- Aerophones
- Idiophones
- Chordophones Correct answer.
Explanation
The Hornbostel-Sachs system classifies instruments by how sound is generated. Chordophones produce sound from vibrating strings, which includes bowed, plucked and struck string instruments.
Question 5Understanding Music
A melody moves from a tonic chord to a subdominant chord and then to a dominant chord. Which harmonic progression is described?
- I – IV – V Correct answer.
- ii – V – I
- I – V – IV
- I – vi – IV
Explanation
Roman numerals label chords by their scale degree relative to the tonic. The tonic is I, the subdominant is the fourth degree (IV) and the dominant is the fifth degree (V), giving I – IV – V.
Question 6Understanding Music
Which dynamic marking indicates a sound that gradually gets softer?
- Sforzando
- Crescendo
- Forte
- Diminuendo Correct answer.
Explanation
Diminuendo instructs the performer to decrease volume gradually over the indicated passage. It is the opposite of a crescendo, which increases volume.
Question 7Understanding Music
A performer plays a melody and then plays it again a perfect fifth higher. What has occurred?
- Inversion
- Transposition Correct answer.
- Retrograde
- Augmentation
Explanation
Transposition shifts an entire melody to a new pitch level while keeping every interval and rhythm unchanged. Moving it up a perfect fifth is a transposition to the dominant.
Question 8Understanding Music
Which texture describes a single unaccompanied melodic line?
- Polyphony
- Heterophony
- Monophony Correct answer.
- Homophony
Explanation
Monophony consists of one melodic line sounding alone with no harmonic support or simultaneous independent parts. It is the simplest of the standard textures.
Question 9Understanding Music
A composer writes a short recurring musical idea that represents a character throughout an opera. This device is known as what?
- An ostinato
- A leitmotif Correct answer.
- A pedal point
- A sequence
Explanation
A leitmotif is a short, recognisable musical idea associated with a particular character, object or idea, and it is transformed as the drama develops. The term is closely connected with nineteenth-century opera.
Question 10Understanding Music
A chord progression moves from the dominant seventh to the tonic. Which cadence does this create?
- Interrupted cadence
- Half cadence
- Perfect cadence Correct answer.
- Plagal cadence
Explanation
A perfect cadence moves from the dominant chord to the tonic, giving a strong sense of final resolution. It is the most conclusive cadence in tonal music.
Question 11Understanding Music
A piece in a minor key uses the raised seventh degree in its final cadence. What is this scale form called?
- Natural minor
- Melodic minor descending
- Dorian mode
- Harmonic minor Correct answer.
Explanation
The harmonic minor scale raises the seventh degree of the natural minor scale to create a leading note a semitone below the tonic, strengthening the final cadence. This raised seventh is the defining feature of the harmonic minor form.
Question 12Understanding Music
A woodwind instrument plays a written C but sounds a major second lower. What is the instrument?
- Horn in F
- Trumpet in B flat
- Piccolo
- Clarinet in B flat Correct answer.
Explanation
A B flat transposing instrument sounds a major second below its written pitch, so a written C sounds as B flat. The clarinet in B flat is a standard example of this transposition.
Question 13Understanding Music
Which form is built on a repeated refrain alternating with contrasting episodes?
- Theme and variations
- Sonata form
- Rondo form Correct answer.
- Through-composed form
Explanation
Rondo form is organised around a recurring principal theme, the refrain, which alternates with contrasting episodes. The pattern is often summarised as ABACA or ABACABA.
Question 14Understanding Music
A choir sings a hymn in which all voices move together in chords with the melody in the top part. Which texture is this?
- Monophonic
- Contrapuntal
- Homophonic Correct answer.
- Imitative polyphony
Explanation
Homophony places a melody in one voice while the other voices provide chordal accompaniment moving in the same rhythm. A hymn sung in block chords is a classic example of this texture.
Question 15Understanding Music
A piece is written in 3/4 time. Which dance style is most closely associated with this metre?
- Reel
- Waltz Correct answer.
- Tango
- March
Explanation
The waltz is characterised by three beats per bar with a strong first beat and lighter second and third beats, matching 3/4 time. Its characteristic accompaniment is a bass note followed by two lighter chords.
Question 16Understanding Music
A melody consists of a phrase, then a second phrase that starts identically but ends with a different cadence. What is this structure called?
- Bar form
- Ternary form
- Parallel period Correct answer.
- Ostinato
Explanation
A parallel period contains two phrases that begin with the same melodic material but end with different cadences, often a weaker cadence followed by a stronger one. The shared opening is what makes the period parallel.
Question 17Understanding Music
Which chord is a diminished triad built on the leading note of a major key?
- The leading-note triad Correct answer.
- The dominant triad
- The tonic triad
- The subdominant triad
Explanation
In a major key the triad built on the seventh degree consists of two minor thirds, making it a diminished triad. It functions as a leading-note chord that resolves strongly to the tonic.
Question 18Understanding Music
A recording shows a melody played by the violins and then repeated by the cellos while the violins continue with a countermelody. Which technique is illustrated?
- Imitation Correct answer.
- Pedal point
- Diminution
- Augmentation
Explanation
Imitation occurs when one part restates material just heard in another part, often overlapping with the original. Here the cellos take up the violin melody while the violins add a countermelody.
Question 19Understanding Music
A composer uses a whole-tone scale. Which harmonic feature is most likely to result?
- Frequent plagal cadences
- Absence of a leading note Correct answer.
- Strong perfect cadences
- A clear tonal centre
Explanation
The whole-tone scale divides the octave into equal whole tones, so no semitone exists between any two adjacent degrees. Without a semitone below the tonic there is no leading note, which weakens traditional tonal resolution.
Question 20Understanding Music
A passage moves from a tonic chord to a chord built on the flattened sixth degree in a major key. Which technique is being used?
- Modal mixture Correct answer.
- Modulation to the dominant
- Secondary dominant
- Circle of fifths
Explanation
Borrowing a chord from the parallel minor while remaining in the major key is called modal mixture or borrowed harmony. The flattened submediant is a common borrowed chord in major-key music.
Question 21Understanding Music
In sonata form, what is the main purpose of the development section?
- To close the movement with a coda
- To restate the themes in the tonic key
- To explore and transform themes through keys and fragmentation Correct answer.
- To state both principal themes for the first time
Explanation
The development section takes material from the exposition and works it through harmonic instability, fragmentation and sequential treatment. It creates tension that the recapitulation later resolves by returning to the tonic.
Question 22Understanding Music
A composer writes a passage where the metre shifts between 5/8 and 7/8 from bar to bar. What is the most accurate description?
- Syncopation
- Irregular metre Correct answer.
- Simple triple metre
- Compound duple metre
Explanation
Irregular metre occurs when the grouping of beats changes from bar to bar rather than remaining constant. Alternating bars of five and seven quavers produce this shifting pattern.
Question 23Understanding Music
A twelve-bar blues uses which basic harmonic pattern in its standard form?
- ii – V – I repeated four times
- I – IV – I – V – IV – I Correct answer.
- I – vi – IV – V throughout
- I – V – I – IV throughout
Explanation
The twelve-bar blues follows a fixed three-phrase pattern of four bars each, built on the tonic, subdominant and dominant chords. A common form is I – IV – I – V – IV – I across the twelve bars.
Question 24Understanding Music
A melody is inverted and also played in retrograde. What has been done to the original?
- The melody is played in canon by two voices
- The intervals are turned upside down and the order of notes reversed Correct answer.
- The melody is raised in pitch and shortened in rhythm
- The melody is harmonised in thirds
Explanation
Inversion reverses the direction of every interval, so rising figures fall by the same amount. Retrograde reverses the order of the notes in time, and combining the two produces a retrograde inversion.
Question 25Understanding Music
A work uses a tone row in which each of the twelve chromatic pitches appears once before any is repeated. Which compositional technique is this?
- Serialism Correct answer.
- Impressionism
- Aleatory music
- Minimalism
Explanation
Serialism organises pitch using an ordered row in which all twelve chromatic notes appear before repetition, ensuring no pitch is favoured. The row may then be transposed, inverted or retrograded.
Question 26Understanding Music
Which term describes the organisation of beats into recurring groups of strong and weak pulses?
- Metre Correct answer.
- Timbre
- Articulation
- Dynamics
Explanation
Metre is the underlying pattern of strong and weak beats that recurs bar after bar, and the time signature records it. The other terms concern tone colour, loudness and the way notes are attacked, none of which describes beat grouping.
Question 27Understanding Music
A melody moves mostly by small steps between adjacent scale degrees. Which term best describes this motion?
- Conjunct Correct answer.
- Disjunct
- Angular
- Chromatic
Explanation
Conjunct motion proceeds stepwise between neighbouring scale degrees, giving a smooth melodic line. Disjunct motion leaps between notes that are not adjacent, and chromatic motion specifically uses semitones outside the prevailing scale.
Question 28Understanding Music
A composer marks a passage 'sforzando'. How should the performer play it?
- Detached and short, with silence between notes
- With a sudden strong accent on the note Correct answer.
- Gradually becoming louder over several bars
- Very softly throughout the phrase
Explanation
Sforzando directs a sudden forceful accent on a single note or chord, often written sfz. It is an accent rather than a gradual change of level or a manner of articulation.
Question 29Understanding Music
Which interval is formed between the tonic and the fourth degree of a major scale?
- Minor sixth
- Major third
- Perfect fourth Correct answer.
- Perfect fifth
Explanation
In a major scale the fourth degree lies five semitones above the tonic, producing a perfect fourth. The third degree gives a major third and the fifth degree a perfect fifth, so those intervals belong to different scale degrees.
Question 30Understanding Music
Which instrument family is the primary source of the sustained harmonic accompaniment in a standard symphony orchestra?
- Brass
- Percussion
- Strings Correct answer.
- Woodwind
Explanation
The string section, with its large numbers and sustained bowing, traditionally supplies the harmonic bed of orchestral writing. Brass, woodwind and percussion add colour, weight and rhythmic definition rather than the continuous harmonic foundation.
Question 31Understanding Music
What does the term 'a cappella' indicate about a performance?
- Singing without instrumental accompaniment Correct answer.
- Singing a single melodic line in unison
- Singing in a chapel acoustic
- Singing in a very soft dynamic
Explanation
A cappella means choral singing with no instrumental accompaniment, so the voices alone carry melody and harmony. It says nothing about loudness, the building used, or the number of parts.
Question 32Understanding Music
Which term describes the speed of a piece?
- Texture
- Tempo Correct answer.
- Tonality
- Timbre
Explanation
Tempo is the rate at which the music moves, indicated by terms such as allegro or adagio or by a metronome mark. The other terms concern tone colour, the layering of parts and the key system respectively.
Question 33Understanding Music
A chord consists of the notes C, E flat and G. Which chord quality is this?
- Minor triad Correct answer.
- Major triad
- Augmented triad
- Diminished triad
Explanation
A minor triad has a minor third above the root followed by a major third, which is exactly the spacing of C to E flat and E flat to G. A major triad would require E natural, while diminished and augmented triads alter the fifth.
Question 34Understanding Music
In a major key, which scale degree most commonly serves as the bass of the dominant chord?
- The fifth degree Correct answer.
- The seventh degree
- The second degree
- The fourth degree
Explanation
The dominant triad is built on the fifth degree of the scale, so its root and usual bass note is that fifth degree. The second, fourth and seventh degrees produce chords of other functions such as supertonic and subdominant.
Question 35Understanding Music
A passage in 6/8 time is performed with the main accent on beats 1 and 4. Which feel does this create?
- An irregular feel with five main beats
- A simple quadruple feel with four main beats
- A compound duple feel with two main beats Correct answer.
- A simple triple feel with three main beats
Explanation
In 6/8 the bar divides into two groups of three quavers, so the primary accents fall on beats 1 and 4, giving two dotted-crotchet beats. Triple and quadruple feels require three or four main beats per bar, and five beats do not fit the grouping.
Question 36Understanding Music
A composer harmonises a melody using chords built only on the first, fourth and fifth degrees of the scale. Which three functions are being used?
- Tonic, supertonic and mediant
- Tonic, subdominant and dominant Correct answer.
- Subdominant, submediant and leading note
- Mediant, dominant and submediant
Explanation
Chords on the first, fourth and fifth degrees are the primary triads, named tonic, subdominant and dominant. They contain all the diatonic notes of the key and therefore can harmonise most simple melodies.
Question 37Understanding Music
A melody in a major key is harmonised so that the final chord is the chord built on the sixth degree. What effect does this create?
- An interrupted cadence Correct answer.
- A plagal cadence
- A perfect cadence
- A half cadence
Explanation
A cadence that moves to the submediant instead of the tonic is an interrupted, or deceptive, cadence, and it leaves the phrase feeling unresolved. Perfect and plagal cadences both end on the tonic, while a half cadence ends on the dominant.
Question 38Understanding Music
A passage uses a repeated rhythmic pattern that stays the same while the pitch content changes. Which term describes this pattern?
- Tessitura
- Rubato
- Ornament
- Ostinato Correct answer.
Explanation
An ostinato is a figure repeated persistently, often as an accompaniment, while other elements of the music change. Rubato concerns flexible tempo, tessitura the general range of a part, and ornaments are decorative additions to a line.
Question 39Understanding Music
A composer doubles a melody at the interval of a third above. Which texture results if the two lines move together throughout?
- Heterophonic
- Monophonic
- Polyphonic with imitation
- Homophonic with parallel motion Correct answer.
Explanation
Two lines moving together in the same rhythm form a homophonic texture, and when the interval stays constant the motion is described as parallel. Imitation requires the lines to enter one after another with the same material, and monophony has only one line.
Question 40Understanding Music
Which scale is made up of alternating tones and semitones?
- Whole-tone scale Correct answer.
- Chromatic scale
- Pentatonic scale
- Octatonic scale
Explanation
The whole-tone scale contains only whole tones, so consecutive degrees are always a tone apart. The octatonic scale alternates tones and semitones, the chromatic scale uses only semitones, and the pentatonic scale uses five notes.
Question 41Understanding Music
A piece is marked 'alla breve'. How is it normally counted?
- Three crotchet beats per bar
- Two minim beats per bar Correct answer.
- Six quaver beats per bar
- Four crotchet beats per bar
Explanation
Alla breve, or cut time, is written with a C crossed by a vertical line and is counted in two minim beats per bar. This gives a broader pulse than the four crotchet beats of common time.
Question 42Understanding Music
A melody rises by a major sixth and then falls by a minor third. What is the total interval between the starting note and the final note?
- A minor sixth
- A perfect fifth
- A perfect fourth Correct answer.
- A major third
Explanation
A major sixth spans nine semitones and a minor third spans three, so the net movement is six semitones upward, which is a perfect fourth. Adding and subtracting semitone counts is the reliable way to combine intervals.
Question 43Understanding Music
A composer writes a melody, then repeats it with the rhythm unchanged but each note replaced by the note a third below. Which transformation has occurred?
- Augmentation
- Inversion
- Retrograde
- Transposition Correct answer.
Explanation
Moving every note by the same interval while keeping the rhythm intact is transposition, which changes the pitch level but preserves the shape. Inversion mirrors the contour, retrograde reverses the order, and augmentation lengthens the note values.
Question 44Understanding Music
Which term describes a texture in which a melody is accompanied by chords that move in the same rhythm as the melody?
- Monophonic
- Polyphonic
- Canonic
- Homophonic Correct answer.
Explanation
A homophonic texture presents one dominant melody supported by chords that move largely in the same rhythm, often described as melody with accompaniment. Polyphony combines independent lines, monophony has a single line, and a canon is a specific imitative procedure.
Question 45Understanding Music
A passage alternates between 2/4 and 3/4 from bar to bar without any change of tempo. What is this device called?
- Hemiola
- Syncopation
- Polyrhythm
- Changing metre Correct answer.
Explanation
When the time signature itself alternates between bars, the music uses changing metre, also called mixed metre. Syncopation displaces accents within a steady metre, a hemiola temporarily regroups a triple metre into duple, and polyrhythm combines conflicting groupings at the same time.
Question 46Understanding Music
A composer uses a chord built on the flattened seventh degree in a major key, giving a blues-like colour. Which best describes its harmonic effect?
- It borrows a chord from the parallel minor and weakens the tonic pull Correct answer.
- It strengthens the dominant function of the leading note
- It converts the key to the relative minor
- It creates a perfect cadence in the tonic
Explanation
The flattened seventh belongs to the parallel minor and, when used in a major key, adds a modal or blues colour that loosens the strong pull toward the tonic. It does not reinforce the leading note, since the leading note is the raised seventh of the major scale.
Question 47Understanding Music
A composer writes a passage in which three melodic lines enter one after another with the same subject, overlapping before the first has finished. Which texture and device are present?
- Monophony with variation
- Homophony with doubling
- Polyphony with imitation Correct answer.
- Heterophony with drone
Explanation
Overlapping entries of the same melodic subject create imitative polyphony, because the lines are independent and equal in interest. Homophony would require chordal accompaniment under one melody, and monophony would allow only a single line.
Question 48Understanding Music
A sonata-form movement begins with a slow introduction, then presents two contrasting themes, develops them, and returns with both themes in the tonic. Which feature most clearly marks the recapitulation?
- The introduction is repeated in full
- The second theme returns in the tonic key Correct answer.
- The second theme returns in the dominant key
- The themes appear in reverse order
Explanation
In the exposition the second theme normally appears in a related key such as the dominant, and the recapitulation resolves that tension by bringing it back in the tonic. This tonal adjustment, rather than the order of themes or a repeat of the introduction, defines the recapitulation.
Question 49Understanding Music
A composer writes a melody in which each phrase begins one step higher than the previous phrase while the rhythm and shape stay the same. Which technique is being used?
- Sequence Correct answer.
- Ostinato
- Pedal point
- Augmentation
Explanation
A sequence restates a melodic figure at a higher or lower pitch level, often stepwise, while keeping its rhythmic shape. An ostinato repeats a figure at the same pitch, a pedal point sustains one note, and augmentation lengthens rhythmic values.
Question 50Understanding Music
A choir sings a passage in which the sopranos hold the melody while the lower three parts move in chords beneath them, and the whole texture briefly breaks into an imitative passage before returning to chords. Which description is most accurate?
- Monophonic texture throughout
- Polyphonic texture throughout
- Heterophonic texture throughout
- Homophonic texture with a brief imitative passage Correct answer.
Explanation
The chordal support under a dominant melody is homophonic, and the short overlapping entries add a passage of imitation before the chordal writing resumes. A work may therefore combine textures rather than remain in one throughout.
