Abstract: A musical system for stringed instruments based on tuning in fifths in conjunction with component control reduces dissonance and discord while increasing harmony and consonance. In a stringed instrument, the main music-making portion of the string serves to drive the other non-music-making portions or supporting portions of the string. This is particularly true at the end of the string past the stop point toward the fixed end and upward past the nut towards the turnable post controlled by a key. By appropriately selecting and providing adjustment for the stop point, as well as the length of the strings past the bridge, less dissonance arises from the individual string as it is played. A string retainer or the like, as well as a compound head, may serve to provide adjustable or selectable means by which tension on a plurality of strings may be adjusted to provide uniform tension between individual strings. Tuning in fifths provides inter-string harmony.
