Description

System for interacting with a stringed instrument, attachment device and communication method Technical Field The present disclosure relates to a system for interacting with a stringed instrument and an attachment device for a string instrument bow. The present disclosure also relates to a method of communication between an attachment device of a string instrument bow and a console. Background Stringed instruments produce sound through one or more strings that are tensioned and vibrated. Vibrations of strings are usually transmitted to the air through the body of the instrument. The sound output of a string instrument depends on the length, tightness and thickness of the strings. For example, longer strings produce lower tones than shorter strings, tighter strings produce higher sounds than looser strings, and thicker strings produce lower sounds than thinner strings. The violin needs two hands to be matched for playing. The player presses the strings against the fingerboard with a part of the fingertips of the left hand to shorten the vibrating portion of the strings and change the pitch. By placing the fingers at specific positions, the player can emit different notes and play the melody. The right hand holds the bow, which is typically composed of a Bob bow stick, an attachable portion called a horsetail garage (frog), and horsetail hair. The player applies force to the bow and pulls it across the strings, thereby generating friction and vibrating the strings. Right hand skills happens to include controlling the speed, pressure and direction of the bow to produce various tone nuances and bow-carrying skills such as continuous, intermittent and skip/skip. In order to play a string instrument with accurate pitch, the player must compromise the ability to clearly hear the pitch and physically pull out the notes in a consistent manner. The ears of the string instrument player need to be well trained to hear correct and incorrect notes. String instrument players also need to do a lot of exercises to train muscle memory to ensure that the timing and location of each finger placement is accurate.
