Viola-Strings.com is proudly owned and operated by The String Emporium, a trusted resource for string players for over 40 years. While we’re especially known for our upright bass expertise, we also bring that same depth of knowledge and care to violists—offering exceptional value on viola strings, rosin, and cases, backed by the fast, friendly, and expert service musicians have come to expect.
As a family-run business, we take pride in providing personalized support and professional guidance tailored to players of all levels, from students to seasoned performers. We carefully curate our selection to include the most trusted viola string brands, ensuring consistent quality, reliability, and performance. Our longstanding relationships with manufacturers allow us to offer highly competitive pricing without compromising on service.
In response to the growing demand for viola-specific accessories, we’ve created this dedicated platform focused exclusively on viola strings, cases, and rosin. By narrowing our focus, we aim to simplify your shopping experience, making it easier to find the right products quickly and with confidence—supported by knowledgeable assistance whenever you need it.
About the Owner
Hi, I’m Steve Koscica, founder of The String Emporium. I currently serve as Assistant Principal Double Bass with the Phoenix Symphony Orchestra, a position I’ve held for over 40 years. Before moving to Phoenix, I was Principal Double Bass with the Hong Kong Philharmonic Orchestra for four years.
In addition to my orchestral background, I’ve performed as a jazz musician for over 30 years, bringing a deep passion for music to everything we do at The String Emporium.
