The largest database for alternative guitar tunings on the internet. GTDB has been gathering and publishing information, chords, scales, tabs and now videos on different guitar tunings since 2009
Currently there are 1341 tunings, 398277 chords, 147510 scales and 371 tabs.
Use the search bar above to find specific tunings or search by key, artist, song, open chord, suspended, sus4, minor or modal.
Our newest feature is the custom chord sheets generator
Generate, create, save and edit your own chord sheets for any tuning in the database.
Chord maps are a way to find chords you already know in the Standard EADGBE tuning, then translate the chord shapes you already know into any tuning you want. For instance you may know C Major in Standard, but but playing a C in another tuning requires relearning chord shapes.
Take any chord map in your favourite tuning, choose a few notes from the map that look within reach and you'll have a tonally different sounding chord but it will be C Major you was looking for.
As with chords above, an array of scales have been worked out to correspond with your favourite tuning. From Major to Minor to the more obscure scale like Major Hungarian. From the nut up to the 18th fret scales notes are morked in black with the root marked in green.
Each alternate guitar tuning has 10 scales.
Tune your guitar to any tuning with our guitar tuner.
Tuning is easy by ear. Just click the first guitar tuner button and match your low (E string) to it. The notes on the guitar tuner from left to right are from the lowest to the highest. More information about tuning by ear using our guitar tuners can be found here
Our first official release is a Jazz number by The Majix.
