JazzValve is a practice tool for B♭ trumpet players: triads, scales, ii–V–I and hard bop licks with valve fingerings and playback. The Practice Notes is the writing side of the same project.
How we write
Articles focus on written B♭ trumpet pitches, octave-specific fingerings and practical jazz exercises.
Practice suggestions describe what to listen for without implying every example has been personally tested.
Articles carry an author and a last-updated date. Review credits are included only when a review is documented.
No invented statistics, no fake testimonials, no claims we cannot back up.

Justin Comstock
