Alternate Tuning Systems in Pure Data (Pd). The library is designed for tuning system demonstrations and how to build them with Pd in the music technology or music theory classroom.

This MATLAB code creates a graph of all possible four-note chords in specified scales, performs a random walk on the graph, and outputs the results to a LaTeX file using PSTricks, which the user then compiles into an eight-page exercise in chord voicings and modulation for guitar. (See the PDF file for a completed example.)

A free, interactive reference for learning scales, modes, chords, arpeggios and exact voicings on Ableton Note and Push pad layouts. It runs entirely in the browser: no account, installation, analytics or tracking.
