Bowed Strings
Violin, viola, cello, double bass — and beyond.

The bowed string family is built around a simple but demanding technique: drawing a tensioned bow across a string to set it vibrating continuously, rather than plucking or striking it once. That continuous vibration is what gives bowed instruments their long, sustained, voice-like quality, and it is also what makes them some of the more demanding instruments to learn, since both hands must work independently and there are no frets to mark exactly where a pitch sits.
In the Western classical tradition, this family is anchored by the violin, viola, cello, and double bass, four instruments built on the same basic design but scaled to different ranges. Interestingly, the double bass breaks from its relatives by tuning in fourths rather than fifths, a detail covered in our dedicated article on the instrument. Beyond the orchestral family, this category also covers bowed instruments from other traditions, including the two-stringed, fingerboard-less erhu, which is bowed with the hair passing between its strings rather than over them — a genuinely different mechanical approach worth understanding on its own terms.
Because technique is so central to this family, we pay particular attention here to the bow itself: how its hair, rosin, and the player's arm control tone, and how different bowing approaches change the character of a single sustained note. We also address electric and electro-acoustic adaptations, such as the electric violin, which keeps the same fingering and bowing fundamentals while trading the resonant wooden body for a pickup and amplifier.
Size is another thread worth watching across this category. Fractional instruments, sized down from a full violin, viola, or cello, exist specifically so younger or smaller players can maintain correct posture and reach rather than straining to fit an adult-sized instrument. We touch on this briefly here and cover it in more depth in our Choosing and Learning category, since getting the size right matters for comfort well before it matters for tone.
The five articles here cover how the violin works mechanically, how the violin and viola compare in size and role, a beginner-oriented introduction to the cello, the double bass's place in both orchestral and jazz settings, and how different bows and bowing techniques shape tone across this family. Each links to the relevant instrument profiles in our library and, where useful, to playing-technique articles that go deeper into specific bowing approaches.
