How to do trills
A trill is a rapid alternation between the written note and the note a step (whole or half) above it, produced by quickly lifting and dropping the upper finger while the lower finger stays down. A good trill is even, relaxed, and clear, with the trilling finger fluttering from the base knuckle rather than a tense hammer from the middle joint. Trills are ubiquitous ornaments in Baroque, Classical, and Romantic repertoire and are a direct test of finger independence and relaxation. Even, clear trills signal a free, well-trained left hand.
How to practice it
- 1Start slowly to lock the intonation of both the main note and the upper (trilling) note.
- 2Lift and drop the trilling finger from the base knuckle, keeping the finger curved and close to the string, like a light hammer tap.
- 3Build speed with rhythmic cells: quarters, then eighths, then sixteenths, then thirty-seconds, keeping the rhythm even rather than rushing.
- 4Increase the number of notes per group over time (four, then six, then eight) and use dotted rhythms to develop finger mobility.
- 5Keep the hand relaxed and let the finger flutter freely; check that the lower finger stays planted and the hand does not clench.
Common mistakes
- Tensing the hand, which makes the trill slow, stiff, and uneven.
- Trilling from the middle finger joint instead of the base knuckle, reducing speed and clarity.
- Letting the upper note go out of tune because intonation was not locked at slow speed.
- Uneven, lumpy rhythm from chasing speed before evenness.
