OnSong Manual

Style Preferences Menu

The style preferences menu allows you to change the look of the current song as well as change the key, capo and chord diagrams.


OnSong works best with text-based chord charts since the app can control all aspects of drawing the page on the screen. If you are using imported file formats such as PDF files, this menu is not available. One exception is if you are viewing SongSelect PDF chord charts. In that case, OnSong will present the Transpose and Capo Menu instead.

Applying Styles

While this menu allows you to style the currently selected song, you can also change the look or other songs in your library. Tap on the ... button in the upper right corner to apply the current style to songs in various books, sets or to set the default look for newly imported songs.

For additional song formatting settings, tap on the wrench icon in the upper-left corner to adjust Song Formatting Settings.

The following items may be changed in the song:

Font Family

Four buttons on the top of the menu allow you to choose the font of the entire song. You can choose from:

  • Georgia is a serif font that may be easier to read for some users.
  • Helvetica is a sans-serif font that is perfect for displaying chord charts. Default.
  • Courier is a fixed-width font that is useful in some cases for aligning chords.
  • Marker is a handwritten font that is very narrow, allowing more content to fit on the page.

Font Sizes

Below the font family buttons are four sliders. Each one allows the size of different elements on the chord chart to be adjusted. To the right of each is a power button. To turn off one of the items in the list, tap until it turns grey. Tap and slide anywhere in the slider control to adjust the value. Tap on the left or right side of the slider to fine-tune adjust each value by one point.

  • Header is the title of the song. You can adjust the font size from 12 to 38 points. Default is 21 points. Turn the header off to have more room on the page for chords and lyrics.
  • Metadata is the artist of the song, key, tempo and time signature. This appears below the header. Turn this off, or reduce its size to make more room for chords and lyrics. You can adjust the size from 6 points to 30 points. Default is 14 points.
  • Lyrics are nearly everything else on the screen. Turn these off if you just need to play the instrument. You can adjust the size from 6 points to 30 points. Default is 14 points.
  • Chords appear above or within lyrics and can be styled separately to make them more visible. Turn chords off for vocalists or musician who memorize their music. While more options are found below, you can change the size from 6 points to 30 points. Default is 14 points.

Line Spacing

When you want to fit more onto the screen, consider reducing the line spacing, or space between lines. You can also increase the line spacing for more room between lines for better visibility. You can tap on the icons to the left and right of all sliders to fine-tune adjust each value. Adjusts between 0.7 and 1.3 lines. Default is 1.0.

Low Light Mode

Tap on the icon to the right of the line spacing slider to toggle low light mode on and off. This will cause chord charts and menus to appear as light text on a dark background. This is applied throughout the app and is useful when playing in a dimly lit venue to reduce light wash and eye strain.

Chord Highlight

This is the color of the background for chords used to highlight them from the page background. Default color presets in the chord highlight palette are the following with a 50% opacity: Clear (default), yellow, orange, green, turquoise, purple, magenta and grey. You can add and customize colors in the chord highlighting palette using the Color Picker.

Chord Style

This allows you to set a color for the chord text as well as to make chords italic or bold for greater visibility. It's recommend that either highlight colors or text colors be used to highlight chords as some combinations may be hard to read. Color presets for text colors include: Black (default), red, blue, green, light blue, and purple. You can add and customize colors in the text color palette using the Color Picker.


The transpose slider allows you to set the key of the chord chart. This can be different than the metadata written in the song editor as transposition is performed. Move the slider from the left to the right to go from C through Cb. To turn off the transposition engine, tap on the power button on the right side. This will display the chord chart as it appears in the song editor as long as no capo is applied.

OnSong is also able to display numeric chords in addition to alphabetic variations. Please see Alternate Keys for configuring OnSong to show numeric chords.

You can tap on the icons to the left and right of the transpose slider adjust the key up or down by one half step.


The capo slider allows OnSong to adapt the chords based on capo position. This maintains the key of the song found in the transpose slider but alters the chords to work with the capo. You can capo from 0 to 11 and determine if the capo is applied by toggling the power button on the right.

By default, increasing the capo slider will modulate the chords of a song down. The reason for this is to allow the declared key of the song to be maintained. For instance, if the key of the song is C#, and a capo is applied on the first fret, then you should set the capo slider to 1. This will display the chords of the song down one half step in the key of C.

You can change how capo effects your chord chart in Settings Display Settings Song Formatting Capo.

You can tap on the icons to the left and right of the capo slider to adjust the capo up and down one fret.


Diagrams can be drawn on the chord chart to help when you play, or for printing chord charts for educational purposes. You turn chords on and off with the power button to the right of the slider. Use the slide to adjust the size of the diagrams to fit between 4 and 10 diagrams across the width of the page.

You can change the diagram instrument by either tapping on chords or diagrams in the song viewer, opening the Chord Inspector. Here you can browse chord formations on different instruments. When the chord inspector is closed, the chord chart is redrawn with the last selected instrument's chord diagrams.

You can change how chord diagrams are drawn on the chord chart in Settings Display Settings Song Formatting Chord Diagrams

You can tap on the icons to the left and right of the slider to adjust the number of diagrams.


Note: Changes made in this menu are applied on top of the original content of the song as found in the song editor. For instance, if you set the key in the song editor and apply transposition, the original content is not effected.

When you select a song in the All Songs list, the changes are applied to the master library. If you select a song in a set that has Separate Set/Song Styles enabled, the changes are only applied to the song within that set. This allows you to transpose a song in a different key when present in a different set.
