MTLE Vocal and Instrumental Classroom Music (K-12) cheat sheet

Form identification rule: if the opening material returns after contrasting material and is followed by a closing section, label it ABA (ternary); if the return is followed immediately by the end, label it binary rounded.

Cadence decision rule: authentic = V–I, half = ends on V, plagal = IV–I, deceptive = V–vi; a cadence ending on I but with the melody on scale degree 3 or 5 is still authentic, not half.

Texture classification: monophonic = one melodic line; homophonic = melody plus chordal accompaniment; polyphonic = two or more independent simultaneous lines; heterophonic = simultaneous variants of one line.

Motive vs. theme vs. phrase: motive is the shortest recognizable rhythmic/melodic unit (often 2–5 notes); phrase is a complete musical thought ending in a cadence; theme is a phrase or group of phrases that opens a section.

Rhythmic dictation strategy: first notate the beat grid and the attack points, then add duration values; check that every measure sums to the meter's beat count before adding pitches.

Interval and chord quality in aural identification: count half steps from the lower note, then apply the major/minor/perfect quality label; for seventh chords identify triad quality first, then the seventh (major, minor, diminished).

Score-reading error detection: compare the performed pitch to the notated pitch by line/space; the most common errors are key-signature omissions and octave displacement.

Melodic contour terms: ascending, descending, arch (rise then fall), inverted arch (fall then rise), and static; use contour plus cadence placement to decide phrase boundaries in listening examples.

Key-signature rule: sharps appear in the order F C G D A E B; flats in B E A D G C F; the last sharp is scale degree 7 of the major key, and the second-to-last flat names the major key.

Circle of fifths: moving clockwise adds one sharp (or removes one flat); moving counterclockwise adds one flat; relative minor is a minor third below the major tonic.

Triad construction: major = root + M3 + P5 (4 + 3 semitones); minor = m3 + P5 (3 + 4); diminished = m3 + d5 (3 + 3); augmented = M3 + A5 (4 + 4).

Seventh chords: major seventh = M3 + P5 + M7; dominant seventh = M3 + P5 + m7; minor seventh = m3 + P5 + m7; half-diminished = m3 + d5 + m7; fully diminished = m3 + d5 + d7.

Diatonic triad qualities in major: I ii iii IV V vi vii°; in natural minor: i ii° III iv v VI VII; harmonic minor raises 7, giving V and vii°.

Inversion figures: root position = 5/3 (triad) or 7 (seventh); first inversion = 6 or 6/5; second inversion = 6/4 or 4/3; third inversion (sevenths only) = 4/2.

Transposition rule: to transpose up by an interval, add that interval to every pitch and adjust the key signature; keep the same scale-degree relationships so the melody remains diatonically equivalent.

Meter classification: simple = beat divides into two (2/4, 3/4, 4/4); compound = beat divides into three (6/8, 9/8, 12/8); asymmetrical = irregular beat groupings (5/8, 7/8).

Voicing rule for four-part writing: keep adjacent upper voices (soprano–alto, alto–tenor) within an octave; bass–tenor may exceed an octave; avoid voice crossing and overlap.

Doubling rule: in root-position major and minor triads, double the root; in first inversion, double the soprano or root; in diminished triads, double the third; never double the leading tone.

Parallel motion prohibition: avoid parallel perfect fifths and octaves between any pair of voices; direct (similar) fifths and octaves are permitted only if the upper voice moves by step.

Range guidelines for SATB: soprano C4–G5, alto G3–D5, tenor C3–G4, bass E2–C4; write within these to keep parts singable in choral arrangements.

Instrument transposition: B-flat instruments (trumpet, clarinet, tenor sax) sound a major second below written; E-flat instruments (alto sax) sound a major sixth below; F instruments (horn) sound a perfect fifth below.

Arranging texture layers: melody, countermelody, harmonic pad, bass line, and rhythmic ostinato; assign each layer to a distinct register or timbre to prevent masking.

Form templates: strophic (A A A), binary (AB), ternary (ABA), rondo (ABACA), theme and variations (A A1 A2 A3), and 12-bar blues (I–I–I–I–IV–IV–I–I–V–IV–I–V).

Motivic development techniques: sequence (restate at a different pitch level), inversion (reverse direction), retrograde (reverse order), augmentation (double note values), diminution (halve note values), and fragmentation.

Medieval (c. 500–1400): Gregorian chant (monophonic, modal), organum, and the Ars Nova; Machaut's Notre Dame Mass is a landmark of the period.

Renaissance (c. 1400–1600): imitative polyphony, the mass and motet, and madrigals; Josquin, Palestrina, and Byrd are central figures; texture is predominantly a cappella vocal polyphony.

Baroque (c. 1600–1750): basso continuo, terraced dynamics, ritornello form, fugue, and the concerto grosso; Bach, Handel, and Vivaldi are central.

Classical (c. 1750–1820): sonata form, balanced phrases, homophonic texture, and the string quartet; Haydn, Mozart, and Beethoven define the style.

Romantic (c. 1820–1900): expanded orchestra, chromatic harmony, program music, and the Lied; Schubert, Chopin, Berlioz, and Wagner are representative.

Twentieth century and beyond: impressionism (Debussy), expressionism/Second Viennese School (Schoenberg, Berg, Webern), neoclassicism (Stravinsky), and American vernacular styles (jazz, blues, gospel).

World music identifiers: gamelan (Indonesia, metallophones and gongs), raga and tala (India, melodic framework and rhythmic cycle), maqam (Middle East), and mariachi (Mexico, trumpets and violins with guitar).

Cultural context rule: attribute a style to its function (sacred vs. secular, court vs. folk, ritual vs. entertainment) before naming composers, because function often determines instrumentation and form.

Conducting pattern rule: 2/4 = down, up; 3/4 = down, out, up; 4/4 = down, left, right, up; 6/8 = down, left, left, right, right, up; the downbeat is always the ictus at the bottom of the pattern.

Ictus and rebound: the ictus is the point of beat; the rebound is the upward motion after the ictus; legato uses a rounded rebound, staccato a crisp ictus with minimal rebound.

Cueing: prepare with an eye contact and a breath or gesture one beat before the entrance; the cue gesture mirrors the entrance's dynamic and articulation.

Dynamic conducting: crescendo is shown by an expanding gesture path, decrescendo by a contracting one; keep the beat pattern intact while changing the size, not the shape.

Posture fundamentals: feet shoulder-width, knees unlocked, weight forward, shoulders relaxed, and instrument held so the airstream or bow path is unobstructed.

Breathing pedagogy: diaphragmatic breathing with the rib cage expanding laterally; for winds, mark breath points in the score and plan them before rehearsal.

Rehearsal sequencing: warm-up, tuning (concert B-flat or A), slow technical passage work, then full run-throughs; isolate the smallest problematic unit rather than repeating the whole passage.

Assessment rubric dimensions: tone quality, intonation, rhythm, articulation, dynamics, phrasing, and posture; score each separately so feedback is specific and actionable.
