Getting louder, getting softer
A single letter sets a level. To change the level while you play, the page gives you two tools: a word — cresc., dim. — or a shape, the hairpin.
The word and the shape
- cresc. (crescendo, "growing") — get louder. Often trailed by a dashed line: cresc. _ _ _ _ — showing how far the growth runs.
- dim. (diminuendo) or decresc. (decrescendo) — get softer, the same way.
- The hairpin: two lines that open
<toward the loud end and close>toward the soft end. It sits under the staff, stretched across exactly the notes it applies to.
The hairpin carries more information than the word: its length tells you over how many
notes to spread the change, and where it ends tells you where you're aiming — the loudest
point of a <, the quietest of a >.

Slow growth — poco a poco
Try it
Try
Play the four-note rise D–E–F♯–G on the D string. Give each note a hair more bow speed than the one before — same weight, just faster travel. Four small increases add up to a crescendo you built, evenly, rather than a loudness you flipped on at the top.
The usual mistake
Saving the whole change for the last note — three quiet notes and then a loud one is not a
crescendo, it's a step. Spread it. Second: ignoring where the hairpin ends — that point is
the target, and if you peak early you've nowhere to go. Third: reading a long closing hairpin
> as an accent. An accent > sits on one note; a diminuendo hairpin stretches across
several. Check how wide it is.
