## What is In Key?

In Key was made to help guitarists who enjoy composing their own songs. The app provides an intuitive user interface that allows a composer to quickly see the chords and notes that are contained in a selected key. This will be a big help to less experienced musicians and will ensure that their new songs are always composed in key!

The fretboard view is another great part of the app that is particularly helpful to lead guitarists who are looking to compose a guitar solo or lead riffs. Here a user can see the entire guitar fretboard and which frets correspond to notes that are in the selected key. This view also supports changing the tuning of the guitar!
