Chords: intervals and scales

Chords: Intervals & Scales is a learning tool for piano, guitar, and ukulele that helps you memorize notes, build intervals, and practice scales and modes. It supports ear training via MIDI keyboard or microphone input, and covers solfège, harmony, and reading sheet music as you progress.

Three core exercises—intervals, chords (major/minor/triad/seventh), and scales/modes—guide you through the basics of music theory and real-world playing, including jazz and blues chords. With this trainer, you'll improve notation, listening, and improvisation.
