Start with BPM before arranging
Tap tempo from a reference track, rehearsal recording, voice memo, or sample. Once the BPM is stable, move the idea into your DAW, metronome, looper, or setlist.
Music Tools
Practical browser tools for musicians, producers, and songwriters. Find tempo, generate progressions, and analyze keys without installing anything.
BPM Tapper
Tap along to any beat and estimate tempo, average BPM, tap consistency, and timing spread.
Chord Progression Generator
Generate song-ready chord progressions by key, mode, genre, and mood with Roman numerals.
Song Key Finder
Paste a chord sequence to find likely keys, matching scales, diatonic chords, and outside chords.
Fast Theory Helpers for Real Writing Sessions
Music ideas often arrive before the spreadsheet or DAW session is ready. These tools stay focused on the quick decisions: what tempo is this groove, what progression fits this mood, and what key does this chord loop imply?
Everything runs locally in the browser, so you can use the tools during practice, rehearsal, writing, or production without creating an account or uploading song ideas.
Generate progressions in the key you actually need
Pick a key and mode, then copy chords with Roman numerals so the same idea can be transposed, reharmonized, or shared with bandmates.
Check the key before writing melodies
Paste a chord loop and compare likely major and minor centers. Use the suggested scales to sketch melodies, bass lines, and lead parts that fit the harmony.
