With the best in class chord sheet editor, powerful auto formatting features and built-in chord recognition engine, Song One makes the creation and managing of song sheets easier than ever before.


Master your craft

Instantly transform plain text song sheets into transposable chord sheets with professionally formatted chord symbols and matching chord diagrams. Look up all possible chord positions on the virtual fretboard and customize the number of strings, the tuning and optional capo position. Auto-play chords on virtual instruments including piano, church organ or electric guitar with a swipe of a finger and experience a more intuitive way of working with songs.


Compose with ease

Effortlessly add chords to your lyrics with a smart chord matrix. Touch the desired notes on the virtual piano keyboard or fretboard to auto-generate all matching chord symbols with extensions and altered bass notes. Reposition chords via drag & drop and make editing lyrics a breeze with Song One's unique Focus Mode and dynamic chord spacing, which repositions the chords as you type. Find chords that sound great together and explore harmonic fields thanks to an integrated circle of fifths.


Make your mark

Import songs in ChordPro, OnSong and SongSheet Pro format or add your content from webpages using the 'Add to Song One' action extension. Fine-tune the lyrics, chords, tabs and metadata, apply customizable themes and add annotatable header images. Auto-generate chord diagrams for any string instrument in any tuning. Scan your sheet music and import PDFs to add highlights and annotation notes. Enjoy complete access to your entire song catalog on all of your macOS & iOS devices with automatic sync via iCloud.


Perform with confidence

Quickly flip through hundreds of song sheets and create custom setlists with backing tracks. Stay organized with easily maintained set collections and forward your songs to bandmates via AirDrop.
