Anatomy of a Cello: 17 Parts of a Cello

When a person refers to cello parts, they are describing the individual components of a cello. Like all traditional string instruments, a cello produces sound waves through the vibration of strings over a wooden body. All parts of the cello must work together to amplify the sound of the vibrating cello strings.

Cellos are made by luthiers, woodworkers who specialize in the construction of stringed instruments. Most cellos have a spruce top and a maple back and ribs. Modern cellos can be made from other woods. Some are even made of carbon fiber.

At a high level, you can divide the cello into three main parts.

1. 1. The body: The body of a cello contains the top of the cello (usually made of spruce), the back of the cello (usually made of maple), and the ribs (also usually made of maple). F-holes are carved into the top of the cello. The body of the instrument also houses various components like the bass bar, sound post, end pin, bridge, and tailpiece.
2. 2. The neck: The neck of the cello extends upward from the body. The key feature of the neck is the fingerboard, where a player presses down on strings to create precise pitches.
3. 3. The peghead: The peghead is found at the top of the neck. It contains tuning pegs that provide the main tuning function of the musical instrument.

An individual cello can be broken down into individual parts. To understand the cello better, familiarize yourself with some of the essential parts of this musical instrument, listed in alphabetical order.

1. 1. Bass bar: The bass bar is a thin strip of spruce wood positioned inside the cello. It amplifies the lower frequencies of the musical instrument.
2. 2. Bouts: Bouts, also known as "c-bouts" or "bouts and waist," are the deep cuts into the main shape of the cello, located at the middle of the instrument. The upper bout and lower bout make it easier to play the cello with a bow without inadvertently bumping the instrument's body.
3. 3. Bridge: A cello bridge is a piece of wood (usually maple) that supports the strings below the end of the fingerboard and makes them easy to bow. The positioning of the bridge affects the intonation, and the height of the bridge affects overall playability.
4. 4. Endpin rod: An endpin rod (or spike) is a metal rod at the bottom end of the cello. It allows the cello to stand on the floor. It is adjusted using an endpin thumb screw.
5. 5. F-holes: Two F-holes are carved into the top of the cello to improve its resonance. The holes allow string vibrations to easily reach the back of the cello and broadcast back out through the top of the instrument.
6. 6. Fine tuners: A cello's fine tuners are attached to its tailpiece, found where the strings meet the bottom of the cello. Fine tuners, along with tuning pegs at the top of the instrument, adjust the tension of the strings and help keep it in tune.
7. 7. Fingerboard: The fingerboard is where the cellist presses down on the cello strings to sound particular notes. The fanciest cello fingerboards are made of ebony, but other woods, such as rosewood or Brazilwood, are also used. Fingerboards must be made from a single piece of wood.
8. 8. Neck: The neck supports the fingerboard and runs upward from the top of the cello body. Its upper end contains a pegbox and scroll.
9. 9. Nut: The cello nut is a raised piece of wood at the top of the fingerboard, running perpendicular to the neck. It contains four grooves that hold the cello strings in place.
10. 10. Pegbox: The pegbox is at the top of the cello's neck. It contains four tuning pegs, one for each cello string. Strings wrap around these tuning pegs, and the cellist can adjust the pitch of each string by tightening or loosening a peg.
11. 11. Purfling: The purfling is a border around the edge of the top of the cello and the back of the cello. It functions as binding and prevents cracks in the wood.
12. 12. Ribs: The sides of the cello are known as ribs. They hold the cello's shape and create space between the top of the cello and the back of the cello. Better, stronger cello ribs lead to better sound quality.
13. 13. Scroll: A cello scroll is a decorative piece of curvy wood at the top of the pegbox. Its function is more ornamental than practical.
14. 14. Sound post: Inside the body of a cello, a dowel-shaped piece of wood called a sound post supports the body just below the bridge. It connects the top of the cello to the back of the cello and provides greater resonance and sound quality.
15. 15. Strings: Cellos have four strings that are tuned in fifths. Their pitches, from lowest string to highest string, are C, G, D, and A. Traditional cello strings were made from catgut (actually sheep gut), but most modern strings are made from metal alloys.
16. 16. Tailgut: The cello's tailgut, or tailcord, is a string that connects the tailpiece to the endpin collar. It can be made of nylon or metal.
17. 17. Tailpiece: Cello strings end at the tailpiece, which connects to the bottom of the cello using a tailgut string. The tailpiece houses the fine tuners, with a tuner for the C string, G string, D string, and A string. Most modern tailpieces are made of boxwood, but cheaper models use plastic composites.

Beyond the main body of the cello, the key component to the instrument is the cello bow. Top cello bows are made of pernambuco wood and strung with bow hair made from a horse's tail. Lower-grade bows can be made from other woods and strung with material other than horsehair. Bow hair is maintained using rosin, which helps the bow smoothly and effectively glide across the cello strings, producing the best possible sound quality.
