A music theory term for a non-chord tone that is held over from a previous chord and then resolved downward. Used in classical harmony.
This chord contains a suspension.
The suspension resolves to the next note.
Compound of 掛 (かける, 'to hang') and 留 (とめる, 'to hold'), referring to a note that is 'hung' from the previous chord and 'held' before resolving. The exact historical derivation is uncertain.
