To work out what scale a song uses, upload a clip and the AI identifies the primary scale or mode (major, minor, dorian, mixolydian, lydian, phrygian, locrian, harmonic minor, melodic minor, pentatonic, blues, and the rest), names the tonal center, and flags any modal interchange or chromatic passing notes that step outside the scale. It goes further than a key finder: knowing a song is in A minor tells you the tonic, but knowing it is actually A dorian explains why the F sharp keeps showing up and why the track feels brighter than a natural minor song should. The analysis also covers the scale's emotional and stylistic associations and why the composer might have chosen it, plus improvisation notes for musicians who want to solo over the track: which scale to base your lines on, which notes to lean on, and which to treat as passing tones.
Upload the song and the AI analyzes the melodic and harmonic material together. Scale identification matches the pitch content against the full catalog of common scales and modes, from the standard major and minor through the church modes to harmonic minor, melodic minor, pentatonic, and blues scales. Tonal center detection establishes which note the music resolves to, which is what separates E phrygian from C major even though they share the same notes. Interchange detection looks for moments the song borrows from a parallel mode or slides through chromatic passing notes, since most interesting songs do not stay perfectly diatonic. The character analysis explains the mood the scale carries (dorian's hopeful minor, lydian's floatiness, phrygian's tension) and why it suits the song. Improvisation notes finish with practical soloing guidance: scale choices, strong chord tones, and notes to handle carefully.
Upload the song and the analysis names the scale or mode, identifies the tonal center, and flags notes that step outside it (modal interchange, chromatic passing tones). It covers the full menu: major, the three minors, all seven modes, pentatonic, and blues scales, with a note on why the writer likely chose that color.
The key names the home base and quality, like A minor; the scale describes the actual pitch collection in use, which is often more specific. A song in A minor might really run A dorian (raised sixth) or A harmonic minor, and that distinction is exactly what your ear notices and a key finder misses.
Yes, and that is the hard part it exists for. Modes sharing the same notes differ only in tonal center and emphasis, so the analysis listens for where the music resolves and which scale degrees do the characteristic work, the raised sixth of dorian or the flat second of phrygian. The result explains which telltale notes settled it.
Borrowing notes or chords from a parallel scale: a major-key song dipping into the minor for one bittersweet chord is the classic case, all over pop and film music. The analysis flags these borrowed moments and names what was borrowed from where, which usually explains exactly why a particular bar hits differently.
Good when there is enough melodic material to establish emphasis; honest when there is not. Short loops, two-chord vamps, and tracks that avoid the distinguishing scale degrees are genuinely ambiguous, and the result says so, offering the plausible candidates. A clip including melody, not just chords, raises the confidence noticeably.
Improvisation notes come with the result: the scale to use, the characteristic notes worth leaning on, and the ones to treat carefully over certain chords. Knowing a track sits in E mixolydian rather than just E major changes which notes feel like home, and that is the difference between guessing and playing.
