Blend feelings into chords, dress them in a genre from blues to MPB, grow them into a whole song. A band behind every idea, on your phone, offline. Harmonaut is a composing tool that starts where songs actually start: with a feeling. Instead of scales, wheels and chord tables, you get a living galaxy of sixteen emotions. Tap Longing, add a little Joy, pull Serenity closer, and the Core hums the key it hears. Forge it, and Harmonaut lays out a chord progression that carries that feeling: the right mode, the right movement, the right extensions, voiced and played back so you can judge it by ear. Then keep shaping. FORGE A TONE • Blend up to four emotions and weight them by dragging them toward the Core • Progressions built from a library of emotional archetypes across seven modes • Depth control: Pure triads, Rich sevenths, or Lush ninths and colour tones • Feel control: hold, pulse, strum, picked or piano comping, plus tempo and key • Genre: Pop, Rock, Hip-hop, R&B, Electronic, Folk, Jazz, Lo-fi, Bossa nova, MPB or Reggae, or let the feeling decide • A melody line written over your chords, shown as a piano roll, rerollable • Reroll for another take on the same feeling HEAR IT PROPERLY • Ten instruments (pad, glass keys, pluck, electric piano, nylon guitar, crunch guitar, organ, bells, strings, flute) and three basses • Drums with fifteen grooves, from a soft pulse and bossa to boom bap, swing, samba, one drop and four on the floor • Bass lines that know the style: walking for jazz, octave for electronic, samba and bossa figures • Five spaces from dry to cathedral and plate • Auto picks all of it from the feeling or the genre; override anything in the Sound sheet RESHAPE ANY CHORD • Shards: smart substitutions for every chord, from relative minors and mediants to secondary dominants, tritone subs and borrowed colour • Change chord lengths, add and remove chords • See the guitar shape for every chord, with alternatives one tap away GROW IT INTO A SONG • The Journey builds an intro, verse, pre-chorus, chorus, bridge and outro from your seed • Tint any section with a different feeling and Harmonaut rewrites its harmony to match • Reorder, duplicate, repeat and regenerate sections • Play the whole arrangement end to end TAKE IT WITH YOU • Guitar sheet PDF: chord diagrams above every bar, fingerings, barres, positions • MIDI export for any tone or full song with chord, bass, melody and drum tracks, ready for your DAW • Copy a chord sheet as text • A library that remembers every tone and song with its mood Harmonaut is built for songwriters, composers, producers and anyone who has a feeling before they have a chord. It runs entirely on your device, with no account and no internet required.

Blues, and a song that follows you while it plays. - Blues joins the genres: a shuffle kit, a boogie bass that walks up the chord and back down through the seventh, a swung guitar shuffle, and a seventh on every chord, because that is the sound - Blues brings its own forms too, twelve bar, quick change, eight bar and minor blues, so a blues idea arrives as a whole chorus instead of a four-chord loop, and its melodies reach for the flat third, fifth and seventh - The Journey scrolls with the music: the section being played comes to you instead of you chasing it - The screen no longer goes to sleep while a tone or a song is playing
