ChordSequence vs Tonaly

ChordSequence is a free set of browser-based music tools for composing and exploring chord progressions. Its player performs chords selected by the user with drums, bass, piano, guitar, and synth, drawing on 548 rhythms that include pop, rock, salsa, and reggae. You can reorder chords, arrange them into sections, loop those sections, and edit individual instrument parts. The mixer offers volume, pan, mute, solo, EQ, and compression controls for each instrument, plus reverb for the overall mix. Songs can be exported as WAV audio or MIDI notes for use in a DAW. Other tools include a chord finder, transposer, key detector, Circle of Fifths, tuner, metronome, guitar and bass tabs, and a drum machine. The browser player is stated to work in Chrome, Firefox, Safari, and Edge. An Android app works offline, needs no account, and supports Android 8.0 or later; iPhone users can use the browser player. The Free plan is free, with all features, no usage limit, and WAV and MIDI export.

Tonaly is a songwriting and practice app that uses the circle of fifths to help musicians find chords, write songs, and learn scales. It highlights chords in a key, suggests progressions, supports borrowed chords and extensions, and helps develop melody ideas for hooks, basslines, or solos. Musicians can practice scales, progressions, and solos with key changes and stepwise difficulty increases. A progression generator, chord audio playback, and chord chart export are also available. Users can export MIDI and PDFs or share song links for collaboration; MIDI export to Ableton, Logic, or GarageBand is listed. Tonaly is available for iPhone, iPad, and Mac, with iOS 16.0, iPadOS 16.0, and macOS 13.0 or later required. Its Mac Pro features include MIDI drag and drop, Core MIDI output, keyboard commands, and lead sheets. The Mac page says iCloud supports working across devices. Tonaly has a free plan and free trial. US App Store purchases include $3.99, paid once for 80+ Scales, $5.99, paid once for PDF lead sheet export, $9.99, paid once for Supporter, $39.99 a year, and $79.99, paid once for Lifetime.
