Cello Lessons for Beginners: Tuning, Sizes and First Notes

The cello has four strings tuned C2, G2, D3 and A3, exactly an octave below the viola, and is played sitting down with the instrument resting on an adjustable endpin. A full-size (4/4) cello has a back about 75 cm (30 in) long; children start on 1/4, 1/2 or 3/4 sizes. Cello music is written mainly in the bass clef.

Works in the UK and the US. This version uses US music words (measure, quarter note, staff); the UK version uses bar, crotchet and stave. · UK version of this page

Key facts

  • Strings, lowest to highest: C2, G2, D3, A3 – tuned in perfect fifths, an octave below the viola.
  • The open C string (C2) is two octaves below middle C.
  • Full-size cello: back length about 75.4 cm (29.7 in). Smaller sizes include 1/8, 1/4, 1/2, 3/4 and 7/8.
  • Music is in the bass clef, with tenor and treble clefs for high passages.
  • In first position: finger 1 is a whole step above the open string, 2 a half step higher, 3 a half step higher again, and 4 a perfect fourth above the open string.
  • The cellist sits; the endpin (spike) rests on the floor.

Cello tuning notes

Press a string to hear its note, bowed. Tick “keep repeating” to hear it again while you tune. Tune the A first, then D, G and C.

How is a cello tuned?

A cello is tuned C2, G2, D3, A3 from the lowest (thickest) string to the highest, each a perfect fifth apart. Tune the A string to 220 Hz, an octave below the orchestra’s A 440, then tune each lower string a fifth below.

GG298.00 Hz
DD3146.83 Hz
AA3220.00 Hz

Use the fine tuners for small changes. The pegs on a cello are big and stiff: turn them gently while pushing in, and ask a teacher to help the first few times.

What size cello do I need?

Most adults and teenagers from about 15 play a full-size (4/4) cello. Younger children play 1/8, 1/4, 1/2 or 3/4 sizes, chosen by height and arm and leg length rather than age. A teacher or string shop should fit the size.

Cello sizes (a guide only: makers’ sizes differ a little)
Cello sizeTypical agePlayer heightBack length
1/84–6under 4 ft (122 cm)17.75–20 in
1/45–7under 4 ft (122 cm)20–23 in
1/27–114 ft to 4 ft 6 in (122–137 cm)23–26 in
3/411–154 ft 6 in to 5 ft (137–152 cm)26–27.25 in
7/8smaller adults–27.25–30 in
4/4 (full size)15 and up5 ft (152 cm) and over30 in (about 75 cm) and over

If you are between sizes, the smaller one is usually easier.

How do you start cello lessons?

Find a teacher, rent a cello of the right size, and learn to sit, hold the bow and play the open strings before adding fingers. Many US schools start cello in grade 4 or 5 through the school orchestra program; private teachers take beginners of any age.

  1. Get a cello, bow, rosin and an endpin stop (a non-slip pad or strap for the floor).
  2. Sit on the front edge of a chair, feet flat, knees bent at about a right angle.
  3. Pull out the endpin so the top of the cello rests against your chest and the C-string peg is near your left ear.
  4. Learn the bow hold: curved thumb under the stick, fingers draped over the top, relaxed wrist.
  5. Play long, even bows on each open string: A, D, G, C.
  6. Add fingers 1, 3 and 4 on the D and A strings, then 2 (see the chart below).
  7. Learn the bass clef notes and play simple tunes with your teacher.

Is cello hard to learn for beginners?

The cello is a friendly first string instrument: you sit comfortably, and the low notes are easy to hear in tune. As with violin and viola, the first months are about posture, a good bow hold and finger placement.

Little and often works best: 15–20 minutes a day beats an hour once a week. Record a few open strings each week and listen to how the sound improves.

Which clef does cello music use?

Cello music is written mainly in the bass clef. For high passages it uses the tenor clef and sometimes the treble clef, which more advanced cellists learn to read.

The open strings in the bass clef: C2 two ledger lines below the staff, G2 on the bottom line, D3 on the middle line, and A3 on the top line. Learn them with Classfern’s bass clef notes unit.
