You can identify the guitar and piano chords at a glance after tapping only twice to search for the chord. In effect, just by tapping two places, you can identify at a glance every root (C-B) and their corresponding type ('maj', 'm7', etc). You can find a chord for Piano in 'Piano Mode' or a chord for guitar in 'Guitar Code'. Regarding the guitar, by touching the buttons 'Up' and 'Down', you can also see a different way of pressing the chords. Moreover, by tapping the '#' button, you can get each sharp chord on the screen. Both for beginners and advanced users, from now on the portable but heavy Chord Book becomes unnecessary. *1.0.1 Update Information [1]Add Creator ID. [2]Fix "C maj" in GuitarMode.
