Music Buddy
Practice, learn, and compose music with one powerful tool.

What you can do
Deep practice tools in one place—notation, play-along, stems, and analysis—for musicians and teachers on every instrument.
Song player & mixer
Play along with multi-track layouts, mute and solo parts, adjust levels, and follow the score with synchronized highlighting.
Audio analyzer
Upload MP3 or WAV files to explore tempo, structure, and harmonic content to help you learn songs and build lead sheets.
Track splitter & stems
Separate vocals, drums, bass, and other parts from a full mix—mute or solo stems for karaoke-style practice, a cleaner backing track, or isolating the line you are working on.
Lessons & learning
Study built-in lesson material, author your own lesson plans, embed notation, print, and share with students or bandmates.
Scales & arpeggios
Generate scale and arpeggio exercises from progressions and patterns, with rhythm options and playback matched to the editor engine.
Metronome
Stay in time with subdivisions and built-in rhythm patterns for practice and rehearsal.
Tuner
Tune with a chromatic tuner using your mic—quick checks before practice or a gig.
ABC notation
Paste ABC to preview, play, and save tunes and exercises—handy for folk, trad, and quick charts.

v2.0.0
Analyze: Split tracks in the browser—then extract, blend, and export
- Isolate vocals, drums, bass, and more into separate tracks—right in your browser, on your machine, with nothing uploaded
- Solo, mute, and A/B each track with its own waveform so you can really hear what the analysis is listening to
- Export any isolated track to MP3 when you want files for the rest of your toolkit
- Zero in on the section you care about: your loop becomes the new song—trimmed, freshly analyzed, and ready before you split into individual tracks
- Build your own mix from the tracks you choose—then export a polished MP3 you can share or drop into any workflow
- Hear the analysis match your ears: run chord and melody detection on exactly the blend you created so the timeline reflects your custom mix
- A sharper, more musical view—waveforms, measure markers, and chord rows now line up perfectly, even right after you extract a passage
- We’ll let you know before a heavy split on a slower device so you’re never surprised by the wait
v1.6.0
Scales & Arpeggios: Richer Patterns & Musical Phrases
- Build more interesting lines with an advance sequence: mix forward and backward steps (like “two up, one back”) instead of a single repeating stride
- New pattern flavors: broken triads, wave shapes, lower neighbors, pentatonic runs, guide tones (smooth 3rds and 7ths over changes), and more
- Optional reverse of any pattern so you hear the same idea upside down
- Target specific beats for chord tones, with several ways to approach them—from a simple snap to chromatic, scale-wise, or classic enclosure figures
- Pattern menu items now show a quick hint of what each shape does, so you can explore without guessing
- Sprinkle in genre-style licks: turn up “Idioms” and the teacher weaves short jazz, blues, rock, pop, Latin, and country phrases into your exercise, matched to the genre you picked for chords
- Guide tones and target-beat options work together so practice stays musical, not just mechanical
v1.5.0
Scales & Arpeggios: Guitar Tab + Chord Toggles
- Scales & arpeggios: guitar tablature toggle with fretboard position selector
- Scales & arpeggios: chord symbols toggle moved to control panel for quick access
