Up to this point, all of the lessons in Time Expressions have required that you immediately change from one dynamic to another. We can make gradual changes in dynamics though, with crescendos and decrescendos. Scroll down for sample practice exercises from lesson 4 of the Time Expressions book.
Crescendo means to gradually play louder. It is represented by two lines like this:
A crescendo can also be indicated with the abbreviation cresc.
Decrescendo means to gradually play softer. It is represented by two lines like this:
Decrescendos can also be indicated with the abbreviation decresc.
Another musical instruction to gradually play softer is diminuendo, which is abbreviated in music with the letters dim.
