Ever hear a song and wonder, "What makes this work?" Songneer tells you — then helps you build something new from it, 100% legally. WHAT IT DOES Songneer is a legal inspiration engine for musicians, songwriters, and producers. Give it any song, and it reverse-engineers what makes the music tick: the melodic contour, harmonic progression, rhythmic feel, and tension arc. Then it searches 800+ public domain works — classical, folk, jazz standards, and world music — to find pieces with a similar sound signature. Finally, it helps you compose a new piece using those public domain building blocks, so your creation is 100% legally safe. HOW IT WORKS 1. ANALYZE — Import an audio file or search Apple Music. Songneer uses on-device ML to transcribe the audio into notes, identify the key and chords, detect instruments, and extract the song's four-dimensional sound signature. 2. COMPARE — See exactly how your song's contour, harmony, rhythm, and tension stack up against public domain matches, with side-by-side visual breakdowns. 3. BUILD — Mix dimensions from different sources. Take the melodic contour from a Bach piece, the rhythmic feel from a folk song, and the harmonic richness from a jazz standard. Apply genre transforms — 25+ styles, from pop and jazz to EDM, reggae, and raga. Adjust creativity sliders to control how far the composition departs from the originals. 4. EXPORT — Preview your composition with multi-track MIDI playback (melody, chords, bass), review every proposed change, then export as audio (M4A) or a standard MIDI file ready for your DAW.
