Music Content Domain 3: Performance, Conducting, and Aural Skills
Domain focus
This domain tests performance, conducting, and aural perception: beat patterns, score reading, transposition, intonation, balance, rehearsal planning, and dictation. Items may ask what a conductor’s gesture means, how a written pitch sounds, or which rehearsal strategy fixes an ensemble problem.
Core rules
- Conducting patterns: 2/4 and 2/2 use a two-beat pattern; 3/4 uses three; 4/4 uses four; 6/8 is usually conducted in two large dotted-quarter beats, not six equal beats.
- Transposing instruments: written C sounds differently. B-flat instruments sound a major second lower; F instruments sound a perfect fifth lower; E-flat instruments sound a major sixth lower (or a minor third higher for E-flat clarinet, depending on register).
- Intonation: tune sustained notes to the ensemble’s tonic; listen for beating between partials; adjust with air support and embouchure, not only slides.
- Rehearsal: isolate the problem, slow the tempo, use count-singing, then restore context.
Worked example
A horn in F has written C4. Because the horn sounds a perfect fifth lower, the sounding pitch is F3. If a conductor gives concert F3 and asks the horn player to read it, the player must transpose up a perfect fifth and finger written C4. Reasoning: transposition is measured from written to sounding, so reverse the interval when going from concert pitch to written pitch.
Traps
Do not treat 6/8 as 3/4 with the same accent pattern. Do not assume all E-flat instruments transpose in the same octave. Do not diagnose intonation without checking whether the problem is pitch, tone, or balance. In score reading, alto clef places middle C on the third line; tenor clef places it on the fourth line.
