Free tools for songwriters and bands
Quick tools for the jobs that come up every practice. They run in your browser — nothing to install, nothing to sign up for.
Chord transposer and capo calculator
Paste a chord chart or a progression and move it up or down by half steps. Lyrics stay where they are. Plus a capo calculator: which shapes to play for any key. Free, no sign-up.
What key is my song in?
Type the chords of your song and find its key, with Roman numeral analysis (I–V–vi–IV) and any chords borrowed from outside the key. Free, works in your browser.
Tap tempo: find the BPM
Tap along to find a song's BPM, then get the delay times in milliseconds for quarter, eighth, dotted eighth and triplet notes. Free, works on phone and desktop.
Song structure builder
Lay out your song's sections — intro, verse, pre-chorus, chorus, bridge, outro — with bar counts, and see when each part starts and how long the song runs at your tempo. Free.
Write it with the whole band
Cobander is free songwriting and recording software that keeps your band on the same song: everyone records and writes from their own computer through the folder you already share, with chords, lyrics and structure on one timeline — and the band levels up as you go.
Free — the whole app, every song, forever. Windows and Mac. More about Cobander.
