Pro-Arte synthetic core cello strings have a warm, dark tone. They are less sensitive to humidity and temperature changes, and break in quickly. Pro-Arte strings are manufactured at a lower tension in order to maximize bow response, tonal blend and playability. Medium tension strings are optimized to the needs of a majority of players.
