#string instruments
- Amati — The name of a famous family of Italian luthiers from Cremona, active in the 16th and 17th centuries, who played a foundational role in designing and perfecting the modern violin structure. Its members include Andrea Amati and Nicolò Amati.
- Violin bow — A regional or obsolete variant for the word 'arcuș' (musical bow); a thin rod of flexible wood equipped with horsehair stretched between its ends, used to vibrate the strings of a musical instrument (violin, viola, cello). In an archaic technical sense, the term could also denote a curved device used in primitive carpentry or turning workshops to impart a rotational movement to structurally machined parts.
- Arco — A term used as a direction in instrumental music, instructing performers of stringed instruments (violin, viola, cello, double bass) to resume playing the notes with the bow, following a structural section where the strings were plucked with the fingers (pizzicato).
- Violin bow — An essential accessory for bowed string musical instruments (violin, viola, cello, double bass), consisting of a thin, slightly curved rod of flexible wood or carbon fiber, between the ends of which a bundle of horsehair is tightly stretched. By rubbing the rosin-treated hairs over the strings, the bow sets them into continuous vibration, generating the sound. In engineering, it denotes a lever or a curved elastic piece used to tension primitive mechanisms.
