The violin is the smallest, followed by the viola, which is only slightly bigger and looks similar. The cello is significantly larger than the first two and the bass is the largest. The size of the strings also varies in both thickness and length, which plays a role in the instrument's range of notes.

A violin is a "little viola", a violone is a "big viola" or a bass violin, and a violoncello (often abbreviated cello) is a "small violone" (or literally, a "small big viola"). (The violone is not part of the modern violin family; its place is taken by the modern double bass, an instrument with a mix of violin and viol characteristics.)

While slightly bigger than the violin, the viola produces a rich and mellow sound that sits between the violin and cello. If you are drawn to lower frequencies and enjoy a supportive role in an ensemble, the viola might be an excellent option for you. For those seeking a more profound and robust sound, the bass is a compelling choice.

Choosing between violin vs. viola vs. cello or bass often comes down to the learning curve associated with each. Violins and violas, with their similar fingerboard layout, demand precise intonation and agility. The more prominent cello, when played upright, requires a different physical approach, blending bowing finesse with finger strength.

Violin strings are much shorter and thinner than bass strings which are several feet long and thick in diameter. Violin has the super high notes all the way to A7 and can play as low as G3. Viola can play from C3-E6, so slightly lower than the violin and not nearly as high. Viola also has a deeper tone than the violin.
