Free tools for musicians

Interactive practice tools built on the same musical taxonomy as the Tonecreek lesson catalog.

Everything here is free and works without an account. The tools compute real music theory - chord tones, scales, target notes and voice leading - and show it where you actually play it: on the fretboard. Start with your own progression, or open one of the worked examples below.

The tools

Known chord progressions

Worked analyses of the progressions you will meet again and again - what the chords contain, which notes connect them, and how to practice them.

Voice-leading analyses

One chord change at a time: the common tones, the half steps and the two notes that carry the resolution.

Scales on the fretboard

Which scale fits which chord, why it fits, and where it stops working - with the fretboard position to try it in.

What is coming next

More curated analyses (chord tones per position, further transitions and keys) and cross-device practice plans for signed-in users. The tools themselves stay free.
