The Instrument
Physics and mechanics. How a lip buzz becomes a standing wave, and why the slide goes out to go lower.
Atlas · An Illustrated Method
A B♭ tenor instrument with an F-attachment. The bell flares forward; the hand slide draws through seven positions; pressing the thumb trigger turns the rotor, diverting the air through the wrapped F tubing for a lower fundamental.

A step-by-step course that teaches one idea at a time on the horn, asks you to prove it, then unlocks the next. From your first buzz to clean, connected playing — your progress is saved.

Physics and mechanics. How a lip buzz becomes a standing wave, and why the slide goes out to go lower.
Seven positions × the harmonic series — every note the horn can play, drawn as a grid you can fly through.
Bass clef from zero, sequenced by harmonic series rather than alphabet. The mic listens.
Smart movement. When you change harmonic series, when you don’t, and the laziest slide between any two notes.
Bb major first — the horn’s home key. Each scale drawn as a path through the grid, with and without the F.
Arpeggios on a monophonic instrument. Outline any chord using only the positions you choose.
Slide cream, rotor oil, monthly bath. Care for the instrument the way the masters did.
Bass · tenor · alto · Bb treble · Eb treble · concert. Read anything, in any clef, any pitch.
Feed in a melody. See multiple ways to play it — efficient, legato, pedagogical, F-optimized.
the method library
Every module is woven with the foundational literature of the trombone — Arban, Rochut and Bordogni, Remington, Kopprasch, Schlossberg. The original notation, untouched. The animated grid and the listening ear, added.
