Arpeggio and Glissando symbols can be found in the "Arpeggios & Glissandi" palette in the advanced workspace. This palette also includes strum arrows, an arpeggio bracket, wind instrument articulations, and slide in/slide out symbols.
To add an arpeggio, glissando etc. to the score, use one of the following methods:
To adjust the length and height of a symbol:
After selecting a symbol, various useful properties can be adjusted in the "Glissando" or "Arpeggio" section of the Inspector.
If needed for future use, you can save the result in a custom palette.
When an arpeggio or strum arrow is added to the score, it initially spans only one voice. To change the height, see Adjust dimensions (above). Playback of the symbol can be turned on or off in the Inspector.
Add the arpeggio to the top staff, select it and use Shift+↓ to extend it downwards to the next stave without it affecting distance between those staves.
Note: For this to work the notes in the 2 staves need to be in the same voice. And it won't affect playback.
A Glissando or, more informally, a slide, spans two consecutive notes. It may be wavy or straight, with or without text. E.g.:
To move an end handle vertically or horizontally, from one note to the next:
Use this command to create cross-staff glissandi. Or to correct the positions of end handles when applying multiple glissandi to chords.
Slide in and Slide out lines can also be found in the "Arpeggios & Glissandi" palette. To edit the length and angle of a line, double-click on it and drag the handle (or use the Inspector or keyboard arrows for finer adjustment).
