I'm wondering if there's a word for the style of guitar on most Reggae songs, when they play chords on the upper strings and mute them after. I would love to know if there's a word for that, that could be used much like you would use "palm muting". For example, you could say "They [insert word I'm looking for here] on that song". Does anyone know if a word for this exists? Thanks!
It seems that the prevailing opinion is to use the word "skank" although I would personally go with the word "chop", as "skank" has another meaning - it is also the name of the type of dance that people do to reggae and ska music.
Using a term such as "reggae off beat chops" on a popular search engine will yield a few results confirming the usage, although admittedly some of them also refer to it as the "skank".
A good thing about the word "chop" is that it is onomatopoeic, so to someone less familiar with the style of music, it is more clear that the sound is short and sharp.
For a fuller description, I guess you could say "off-beat chops".
Perhaps it's worth mentioning that I am from the UK; perhaps the usage differs elsewhere.
I know it as the "skank", though other names are used (see the link). I think it would be reasonable to say "The guitarist skanks on that song" for example.
The term is "skanking" (a la the Marley song "Easy Skanking"), and it's also part of other Jamaican music, such as Ska. You are correct that it's about the high strings. When I've done it, it's been more about muting by releasing tension in the chording hand, rather than with the palm of the picking hand. The picking hand stays loose, keeping with the rhythm.
