Each player/violin combination has a different sound. That is just my “voice”, if you will. It helps if you have a good violin like the ones Michael sells and work toward your own particular voice. I listen to a lot of CDs with different violinists playing the same piece. Each one is different, i.e., unique to the player and their violin.
It does help to have a good violin and learn good technique.
So… keep practicing and find your voice.
