AP Music Theory sight-singing guide
Prepare the hard decisions, then sing without stopping.
Use the preparation window on tonic, meter, leaps, and cadence; hold the pulse through mistakes; then review the recording before generating a fresh melody.
Short answer
Fix the tonic and meter first, rehearse only the leaps and the cadence, choose a tempo you can sustain, and never stop to correct a pitch — pitch and rhythm are scored separately.
Spend the preparation time on decisions, not on the whole melody
The preparation window is short — MIDI Mind mirrors the exam's 75 seconds — so singing the melody straight through from the first note usually wastes it. Preparation is where you make the four or five decisions that keep the performance from collapsing.
Establish the tonic and hear it as a reference you can return to. Read the meter and find where beats subdivide. Then look ahead for the places most likely to fail: the largest leap, any chromatic alteration, the widest rhythmic contrast, and the final cadence.
- 01Fix tonic and the key's scale-degree map before reading rhythm.
- 02Speak or tap the rhythm on a neutral syllable at the tempo you will actually sing.
- 03Sing only the leaps and the notes on either side of them.
- 04Sing the last two measures so the cadence is already secure.
- 05Choose the tempo you can sustain, then start internal counting before you sing.
Keep pitch anchored to scale degrees, not to intervals alone
Interval-by-interval singing accumulates error: one slightly narrow third pulls everything after it flat. Scale-degree hearing gives you a reference that resets on every tonic-defining note, so a single miss stays local instead of shifting the whole melody.
Whatever syllable system you use — movable-do, fixed-do, scale numbers, or a neutral syllable — use it consistently. The system matters far less than whether it lets you name the function of a pitch quickly enough to sing the next one in time.
Protect the pulse even when the pitch goes wrong
Pitch and rhythm are scored separately, so stopping to fix a wrong note trades one error for several. A steady pulse through a wrong pitch usually costs less than a correct pitch that arrives late and pushes every following attack out of place.
Practise the recovery explicitly: sing a phrase, deliberately miss a pitch, and keep going in tempo. The skill being trained is continuing, and it does not develop from performances where nothing goes wrong.
Review a recording before you sing another melody
A performance you did not review teaches very little. Listen back and separate what actually happened: a pitch heard incorrectly, a pitch heard correctly but sung out of tune, a rhythm misread, or a tempo that was never sustainable.
MIDI Mind analyses the recording and shows per-note pitch and rhythm evidence, so the next attempt can target one of those causes. Then retest with a freshly generated melody rather than repeating the one you have now memorised.
Common questions
How long do you get to prepare a sight-singing melody?
The AP Music Theory exam gives 75 seconds to prepare each melody and roughly 30 seconds to perform it; practice here uses the same timing. You may sing aloud while preparing. Check the current College Board exam description for official timing and policy.
Does it matter which solfège system you use?
No. Movable-do, fixed-do, scale numbers, and neutral syllables are all acceptable. Consistency matters more than the choice: use the system that lets you identify a pitch's function fast enough to sing the following note in tempo.
What should you do after singing a wrong note?
Keep the pulse and continue. Pitch and rhythm are assessed separately, so stopping to correct one pitch usually creates additional rhythm errors. Re-anchor on the next tonic-related pitch and carry on.
How often should you practise sight singing?
Short and frequent beats long and rare. Two or three fresh melodies several times a week, each one reviewed before the next, builds more reliable reading than a single long session, because each attempt is on material you have not memorised.
