This trombone slide position chart shows where the slide goes for every note from low E in seventh position to high B♭ in first, in bass clef at concert pitch. Tap a note to see it on the staff and on a slide diagram with all seven positions marked, and the alternate positions shown in a lighter circle.
Alternates such as fourth-position D and F, and sixth-position C, keep fast passages smooth by saving long slide moves. The hear button plays the note, and the full chart below lays out every position at once. It also works for baritone and euphonium players reading bass clef who want to learn trombone.
