Martellato (or martellé in French) is an Italian musical term that means hammered. The word derives from the Italian martello, meaning "hammer."
In string playing, martellato refers to a bowing technique where the bow is pressed firmly into the string and released with a sharp, accented stroke, producing a strong, percussive attack followed by a brief silence before the next note. Each note sounds distinctly separated with a "hammered" quality. It is one of the fundamental bowing techniques alongside legato, staccato, spiccato, and others.
In keyboard and percussion contexts, martellato indicates a forceful, hammered style of striking the keys or instrument.
The other options do not match. "Pinched" in music would be closer to pizzicato (plucked). "Blasted" and "punched" are not standard musical terms.
