Double the Weird Squiggles (You're Welcome)

The Dual Chords Tab—AKA Your Secret Weapon for Confusing Everyone (Including Yourself)

Yo, so this lil' feature lets you enable & configure secondary chords that pop up next to your primary chords on screen. Super handy if you're sharin' a chart with someone who's got a capo (because apparently they can't just memorize like a normal person), or if you're tryna learn some bougie numbering system that makes you sound smart at open mics.

Position

Here's where you tell OnSong where to shove that secondary chord. Before? After? Nowhere? You got options, fam.

  • Off — the secondary chord is chillin' in the corner, not invited to the party. This is the default, AKA we made the choice for ya.
  • First — the secondary chord rolls up before the primary chord. Bold move.
  • Last — the secondary chord shows up after the primary chord, like it's fashionably late.

Whatcha Want It to Look Like

This is where you make your secondary chord look completely different from the primary one (which is totes the default, BTW). Go nuts with font color & choose if it's gonna be bold, italics, or whatever. Don't check nothin'? Congrats, you just get the primary chord's vibe recycled.

ZOMG plot twist: You can also make the colors do that whole psychedelic rainbow thing with Synesthesia by tappin' that rainbow switch at the end. Wanna get *really nerdy? Tap & hold the switch to unlock secret chord color customization. (Psst—Premium subscription required, so yeah, more $$$.)*

Glow-Up Color

Here's where you change the highlight color of your secondary chord so it doesn't look like a sad copy-paste of the primary. By default, nothin's checked & it just copies whatever the primary's rockin'. Tap a checked swatch to uncheck it & boom, back to default.

Plot twist: There's also Synesthesia dynamic highlight colors if you tap that rainbow switch at the end. Tap & hold for a lil' context menu where you can customize colors per chord like you're some kind of chord fashion designer. (Yeah, Premium subscription required. Of course it is.)

Type

Pick which flavor of secondary chord you wanna display. Here's the whole boring menu:

  • Capo — shows what the primary chord looks like when you use a capo. It's like magic, except it's math. Default.
  • Original — shows the chord that was actually written for the song before someone decided to transpose it like a monster.
  • Transposed — shows the chord after ya transpose it accordin' to whatever key you picked. Math again, srsly.
  • Numeric — Nashville numbering system, baby. Shows the chord as a number (1-6) representin' the interval in the key. Fancy & pretentious.
  • Roman — Roman numerals, because regular numbers weren't bougie enough. Same deal—just the interval in fancy letters.
  • Solfege — do-re-mi vibes. Shows the chord usin' that whole vocal syllable thing relative to the key interval. Very classical. Very annoying.

Decoration

Wrap that chord in some text decorations so it doesn't get lost on stage under the lights. Options:

  • None — no decoration, just raw chord. Default. Boring but honest.
  • [ ] — slaps square brackets around it. Official-lookin'.
  • ( ) — wraps it in parentheses, like it's a lil' side comment. Whispers, "Hey, this chord too."
  • < > — angle brackets. Very sci-fi. Very pointy.
  • { } — curly braces. Your chord now looks like code. Congrats, it's a programmer.
