Music for thinking & creating
Endless, quiet music that keeps you in the work. Composed by rules as you listen, and it never needs Wi-Fi.
No subscription
I couldn’t find the music I needed to work. So I made it.
For years my work ritual was the same. Open a playlist, start the task, and ten minutes later a song with lyrics breaks the spell. Or an ad. Or the same track I’ve heard four hundred times.
I wanted something simpler. Music that sits in the background like weather. That doesn’t loop, doesn’t talk, doesn’t ask me to pick anything. That works on a plane.
selftone is that. It’s the app I wanted on my own Mac. I hope it becomes yours too.
— Sergey Hartmann, maker of selftone
Five moods for five kinds of work
Pick what you need. selftone handles the rest: key, tempo, instruments, and how the music grows over time.
Open harmony and lots of air. For problems that need space.
Dorian / lydian · 60–66 BPM · organ pad, upright piano, cello, drone




Written by rules, not by a model
selftone composes in real time the way musicians have for centuries, with scales, chords and structure. No language or music model writes the notes.
A key, a mode, a tempo
Each session starts there. Chords and melodies follow real harmonic rules, so nothing sounds random.
A sampler, not a stream
Piano, cello, marimba, flute and vintage synths play from a library of instrument samples inside the app.
Built note by note
The music is written as you listen. It moves in chapters and never loops.
Every session starts from a new seed, so no two sound the same.
Set a timer, or don’t
Choose 25, 50 or 90 minutes and the music finds its own ending, so you know when to take a break. Or choose endless and let it play all day.
