Chord Notepad
A text editor for musicians that detects the chords in your lyrics and plays them back.
Chord Notepad is a text editor built for musicians. You type out your lyrics with chord symbols above them, the way you'd sketch a song on a scrap of paper, and it detects the chords automatically and highlights them as you write.
The useful part is that you can hear it. Click any chord to play it, or hit play and let the whole song run through at a tempo you choose. It understands everything from plain major and minor chords to the messier jazz voicings: 7ths, sus, diminished, augmented, add chords, half-diminished. The audio comes from FluidSynth, so playback sounds like a real instrument rather than beeps.
It's free and open source under the AGPLv3, with pre-built downloads for Linux, Windows and macOS.
