U+1D173 "𝅳" Musical Symbol Begin Beam Unicode Character

U+1D173 "𝅳" Musical Symbol Begin Beam is a control character used in the standard notation of musical scores to mark the starting point of a beam, which is the thick horizontal line or lines that connect a series of notes, such as eighth notes or sixteenth notes, to indicate they are to be played in the same rhythmic group. Unlike visible musical symbols, this character is non printing and functions as an invisible marker within encoded music representation systems like Standard Music Font Layout (SMuFL), allowing text based music software to correctly group notes together for playback and display.
