Why Does the Concertmaster Coordinate Orchestral Bowings?

An orchestra’s string parts commonly carry agreed up-bows, down-bows and bow changes. Their purpose is not merely to make dozens of bows look neat. Direction determines whether a gesture begins near the frog or the tip, while the amount and speed of bow affect the attack, weight, sustaining capacity and release of a phrase. If some players change near the frog while others continue at the tip, accents and breathing can pull apart.

The concertmaster generally discusses these decisions with the conductor and the other string principals, then ensures that the bowings reach the parts. New York Philharmonic Principal Associate Concertmaster Sheryl Staples likewise describes bowings, phrasing and articulation as central decisions of the concertmaster’s chair. Agreement does not erase individual colour; it supplies a shared grammar of movement. If a crescendo travels through a long up-bow towards a strong beat, for example, everyone must reserve a comparable amount of bow for the same arrival.

Good bowing is therefore not a permanently correct answer. Hall acoustics, tempo, ensemble size and the conductor’s view of the phrase may all prompt changes. What matters to a listener is not visual symmetry but whether the string section can breathe as an enlarged single body, landing together at an accent and retaining direction through an extension. Pianists have no bow, yet face the same musical problem: physical actions become phrasing only when they are organised into audible articulation and time.
