Chord Lookin' Glass

The chords palette is basically your personal chord makeover station. Wanna make your chords look totally different? This is where the magic—and the slight confusion—happens. Affects transposition, how they look, & those fancy chord diagrams everyone pretends to understand.

Vibes

So like, chord charts usually just use boring A-G letters. But OnSong? ZOMG, OnSong can flip those into numbers for all you math-rock nerds out there. The selected style is highlighted because we care (we don't). Pick your poison:

  • Alphabet uses letters A-G with sharps & flats so you know exactly which chord to murder. Might include an H if you're into that weird localization thing. Comes standard.
  • Nashville uses decimals—fancy, right?—to show what number chord you need based on the key. Plus symbols for when chords get weird & moody.
  • Roman uses those fancy Roman numerals everyone learned in 9th grade & immediately forgot. Capital = major chord (happy), lowercase = minor chord (sad). Symbols do the heavy liftin' for modes & stuff.
  • Solfege literally uses do, re, mi, fa, so, la, ti, do instead of numbers like you're in The Sound of Music. Symbols show up when things get weird.

Transpose

Slide this bad boy to move your song to literally any key. C is chillin' on the left, Cb is vibin' on the right. Arrow keys for when you need to be super precise about your key choice (you don't, but we get it).

The power button on the right is your transpose on/off switch. Kill it, & if you ain't got a capo, OnSong just shows the chords exactly as they appear in the Song Editor. Boring, but honest.

Capo

Slider goes 0 to 11—that's every fret, genius. OnSong will automatically wreck your chords to keep the song in the right key even though you're cheatin' with a capo. Wanna change how this happens? Settings » Display Settings » Song Formatting » Capo » Capo Modulates. Buckle up.

Power icon on the right toggles capo application. So you can keep a capo saved & then decide whether to actually use it depending on what instrument you're playin'. Revolutionary (it's not).

Diagrams

Wanna see chord diagrams? Don't wanna see chord diagrams? This is your jam. Slider lets you pick how many show up—anywhere from 4 to 10 across the page. Power icon toggles 'em on & off entirely.

Wanna go deep & customize where these diagrams live? Settings » Display Settings » Song Formatting » Chord Diagrams.

Diagram Position

Where should your diagrams chill on the page? You got options:

  • None kills all diagrams. That's the default.
  • Below plops 'em under your song like leftovers.
  • Above shoves 'em above the lyrics, right under the title & metadata like they own the place.
  • Within jambs diagrams directly where the chords are in the lyrics. Chaotic. We like it.

Instrument

Pick your instrument & watch the diagrams magically rearrange themselves. The selected one gets highlighted because it's special. Choose a different one & BAM—fresh diagrams for your chosen axe.

Transposing Instrument

Your instrument is weird & doesn't play at concert pitch? (Lookin' at you, brass section.) OnSong can adjust all the chords to make it work for your freak show. Options:

  • Off for concert pitch & normal stringed/percussion stuff like piano. Boring but reliable.
  • B-flat for trumpet, clarinet, bass clarinet, & those saxophones of yours.
  • E-flat for soprano clarinet & the fancy saxophones that think they're better.
  • F for French horns, English horns, & other pretentious brass.
  • G for alto flute because apparently that exists.

Note: This palette doesn't actually mess with your song—it just applies these vibes on top of what's already there. We're not monsters.
