Bass trombonists and tuba players: here’s a book full of etudes that will challenge you to play in some interesting harmonies.
Written exclusively for the lower brass, these jazz, classical, and avant-garde pieces are great for auditioning, exercising your sight reading and your ear for more angular and harmonically complex improvising.
Chord symbols are included so that you can play them with others and analyze how certain notes sound over specific chords.

I recommend practicing an etude until it is mastered before attempting to play it with its play-along track.
Without the steady tempo of the accompaniment, you will have the freedom to work on specific areas of the etude that might need to be worked out more slowly.
Also, playing along with the accompaniment track should not necessarily be the main goal or purpose of preparing each etude, but is an additional (and fun) element of the method, should you choose to use it.
