Dynamo Violin strings are ideally suited for Orchestra players, chamber musicians, and soloists. They offer a broad sound and an excellent response. They have a wide dynamic range and you can modulate sound colors all along to their full extent. They sound great on most old and most new instruments. All of the Dynamo Violin strings have a synthetic core; the A string is aluminum wound while the G string is silver wound. The D string comes in both aluminum or silver wound.
