Tig Guitar ยท Guitar & Bass ยท The Key Change Toolkit
Understand your instrument, not just the shapes.
A hands-on toolkit for guitar and electric bass โ the Nashville Number System, harmony, the fretboard, chords, ear, and rhythm. Pick any key, decode any song, and see how it all connects โ built for players who want to know why the music works, and where it lives on the neck.
New ยท Electric Bass
A whole section for bass players.
Four strings, an octave down, and a different job: hold the low end and lock to the kick drum. A curriculum from your first quarter note, the scale and triad shapes with real fingerings, and a song library with a practice guide for every song โ at easy, medium or advanced, with Nashville numbers on the neck.
