Squiggly Finger Maps
Chord diagrams pop up when you tap a chord in the song viewer to open the Chord Inspector, or if you turn on chord diagrams using the Style Preferences Menu. You can tweak how chord diagrams look using these settings. Riveting stuff.

Lefty Vibes
Turn this on & chord diagrams flip so left-handed peeps (yeah, you with the backwards guitar) can play without lookin' like a newborn giraffe. Default is off because, y'know, most of y'all are normal.
Display Bars
Bars are those solid lines stretching across a bunch of strings. They're where one finger gets squished across multiple strings because guitars are mean. OnSong figures this out from the chord variation, or just guesses real hard if you didn't tell it. Turn it off & you only get dots. Boring. Default is on.
Display Fret Positions
The fret numbers show up on the left side of the chord diagram so you don't have to, like, think about where your fingers go. Default is on.
Display Note
The bottom of the chord chart has numbers that match up with the dots in your little fret grid. Pick one:
- Off = absolutely zero info at the bottom. Congrats, you're flyin' blind.
- Finger Position = which finger (1–4: index, middle, ring, pinkie) you're supposed to use. Default. Revolutionary.
- Letter = the actual note name being played. For the nerds in the room.
Show Only Exact Matches
OnSong displays chord diagrams in the Song Viewer & Chord Inspector that match your chord, even if it's got a weird bass note or a funky variation. Flip this on & it'll be all "nope, only EXACTLY that chord" & then you'll have way fewer options. Have fun.
Show Only Preferred Chords
When chord diagrams show up in your song viewer, OnSong pairs 'em to default diagrams based on the chord name. Most musicians know the basic chords, so turn this on & it'll ONLY show diagrams for chords you hand-picked in the Chord Inspector. Revolutionary gatekeeping, basically.
