What is is called when you repeatedly press strings on a guitar and strum at the same time? If you do it fast enough on an acoustic guitar it will make a wah-wah-wah-wah sound. This is without a pedal, or a whammy bar. It probably is basically "bending" the pitch but going downwards instead of sideways. If you do it slower it will essentially make a staccato sound because the fingers mute the strings when you are not pressing on them as hard.
Anyway, I'm guessing it has a name if every single chord has a name, there must be a name for this as well. Thanks!
