Cello

The cello is the second-largest bowed member of the string family, played upright between the knees and braced against the floor with a metal endpin. Its range sits closer to the human voice than any other orchestral string instrument, which is a large part of why cello melodies are often described as sounding especially warm, expressive, or vocal.

In the orchestra, cellos frequently double the bass line an octave above the double bass, reinforcing the harmonic foundation, but they're just as often given rich, singing melodic lines of their own — especially in the Romantic era, when composers leaned heavily on the cello's emotional weight. In a string quartet, the cello anchors the bottom of the texture, alongside the violin and viola.

Alongside its orchestral and chamber roles, the cello has a substantial solo repertoire, including Bach's six unaccompanied Cello Suites — among the most performed and recorded solo works for any instrument.

Where to start listening: Bach's Cello Suite No. 1 (specifically its famous opening Prelude) is the instrument's most iconic solo moment.
