Guitar music often has the sound of suddenly sliding strings, which is very nice, but what is the professional name?

To be precise, it is the rubbing sound when fingers change chords on strings or move handles. Some fricative sounds can be avoided by changing the hand shape, and sometimes they are inevitable because of the particularity of chords or handles. The less rubbing, the better hand shape control and the higher performance level.

Actually, I think this kind of rubbing sound is quite nice. Crystal clear, metallic, and a decorative sound.
