Arps, or arpeggios, are attained by sliding up the scale in half-step increments on most '[[List of Trackers[trackers].  The tracker quickly cascades through specified tones, creating an audible chord.  Arps tend to be limited to three notes : the root note and the two tones specified in the effects column.

If a chord has more than three notes and the tracker only allows three notes in it's arps then the musician must pick a note(s) to omit or place another arp in a different track with the rest of the notes.  In music theory, it is advised to remove the 5th first if a note must be removed.

'[#[Table Arps]
Some trackers rely on tables to build arps.  In this situation the number of notes in an arp may be unlimited.  The arp table might be called from an effect column.

'[#[Chord Arp Value Reference]
The following is a list of chord shapes and the '[[hexadecimal[hex] values for each tone in that chord.  (These should also be effective for '[[MML] languages as well.)
