## What is Fretworks?

Introducing Fretworks for iOS - the easiest way to put names to chords and find their inversions.

With Fretworks in hand, you can:

* Find chord names with detailed interval information by tapping on the fretboard.
* See other ways to play a given chord and it's inversions anywhere on the fretboard, with in line intervals so you can avoid putting sevenths on your bass string - unless that's your thing!
* Save chords so you can refer back to them later - super handy for when you're in class!
* Press a button to hear a chord played back - so you can quickly make informed choices while writing music without having to repeatedly pick up and put down the guitar.
* Change the tuning and number of strings on your instrument - Fretworks will help you find chords and intervals whether you play a standard 6 string guitar, an ERG, ukulele, mandolin or bass guitar.

Fretworks is free with subscriptions for convenience features like infinite automatic inversions.

Use Fretworks to help you become a chord master!

### 5/5 — Great tool for teachers or for lead sheets.

*2024-06-05*

Found this app really handy for quickly re-arranging chord voicings for students, and demonstrating how chord tones work!

It’s powerful enough that intermediate students could use it too.
