Tremolo
Tremolo notation asks for a rapid repeated sound. Slashes through one note stem usually signal repeated attacks on that note; slashes between two stems signal quick alternation between the written notes or chords.
- rapid repetition
- one note or two
- follow the slash placement
How do you read the marks?
Look for short diagonal strokes through a stem or between stems. A single-note tremolo rearticulates the same pitch. A two-note tremolo switches back and forth between the notated endpoints. The note values and the number of strokes guide duration and subdivision; do not assume one universal speed from the word alone.
Is tremolo the same as a trill?
No. A Trill alternates a principal note with a nearby auxiliary note, usually a step above it. A two-note tremolo uses the two written pitches, which can be farther apart. A one-note tremolo does not change pitch at all.
What does the player actually do?
On piano, repeat the key or alternate fingers/notes as written. String players may use rapid bow motion. Guitarists may pick repeatedly. The physical movement differs, but the listener hears a sustained texture built from many fast attacks.
Practice the distinction
Play four slow beats while repeating C evenly within each beat. Then alternate C-G within each beat without speeding up the main pulse. If the rapid pattern hides the beat, slow down and make the subdivisions regular.
