Watch

Hear it and Believe it

When selecting a violin for a child/beginner, sound and tone production are actually NOT that important. Be cool, let me explain it now. A beginner student is working on open strings, basic bow holds, and fundamental rhythm. They aren’t pulling a concert-hall tone out of any level of instrument yet (even with a million dollar stradivarius), this will last for years, not months. If the instrument is heavy, painful, and intimidating, they will quit long before their tone even matters. For a kid, the design logic must prioritize three completely different pillars: Comfort, Playability, and Fun. But having said that, we still want you to hear RedHeart's tone...
