Chord Trainer
Hear and name chords beyond plain triads: 7ths, sus and add chords, extensions and altered dominants, with inversions. Puzzle, training and “imagine” modes, plus a progression sketchpad to loop ideas like Em9 | A13 | Cmaj7#11.
Train your ear and your writing, right in the browser.
Three small apps for musicians and students: chords, counterpoint and dictation.
- Free
- No download or sign-up
- Runs in your browser, phone or desktop
- Works offline after the first visit
Counterpointer
Species counterpoint, first and second species. Write against a cantus firmus (or one of Fux's) and see which rules each note breaks, with hints, fixes and a cheat sheet. Strict (Fux) or relaxed rules, in all church modes.
Dicteeineer
Pitch and melodic dictation. Find single notes on a piano keyboard, with or without a reference, or write generated melodies bar by bar in any key, on treble, bass or grand staff, with optional chromatic notes.
How it works
Open an app and start. Each one installs itself in the browser on the first visit (about 1 MB with the piano sounds), so it keeps working offline. You can also add it to your home screen.
Your progress and settings stay on your device. There are no accounts and nothing is sent anywhere.
A MIDI keyboard works in Chrome, Edge and Firefox. Safari doesn't support Web MIDI, so on an iPhone or iPad you answer on the screen.
