Martellato
Martelé (bowstroke)
Percussive bow stroke
Martelé (French pronunciation: [maʁt(ə)le]; literally meaning "hammered")[1][2] is a percussive bow stroke used when playing bowed string instruments, though the Italian martellando and martellato are also applied to piano and vocal technique, and even (by Franz Liszt) to the organ.[3] The effect is usually produced by holding the bow against the string with pressure, then releasing it explosively to produce a sharp, biting attack with a rest between strokes.[1]
