There's a better way. ↓

Feature 01

Know the key before you play the first note.

Riffscope detects the key signature in real time as the track plays. No more guessing whether that song is in E minor or G major. See it instantly, so you can choose the right scale, capo position, or mode.

✓ Major and minor key detection
✓ Modal identification (Dorian, Mixolydian, etc.)
✓ Confidence indicator so you know when it's ambiguous

Chord timeline

Chord changes highlighted as they happen

Feature 02

Chord changes, live on the timeline.

Watch chord markers roll across the playback timeline in sync with the music. See what's coming up, freeze on a tricky transition, and replay any section until the voicing clicks.

✓ Real-time chord detection with beat-accurate timing
✓ Extended chords: 7ths, sus4, add9, and beyond
✓ Capo-aware transposition — reframe for your instrument

Feature 03 — 04

BPM locked in.
Tabs generated.

Riffscope reads the tempo precisely — down to a decimal — so your practice metronome is always calibrated. And for the actual notes? Generated tabs appear right alongside the chord chart, matched to what the song is playing.

✓ Precise BPM with subdivision markers (8th, 16th notes)
✓ Guitar, bass, and piano tab generation
✓ Export tabs as PDF or share a link
