The violin and the viola belong to the bowed string instrument family, which also includes the cello and double bass. Although they look alike, they differ considerably in size, weight, and range.
Each instrument has its own specific string tuning and presents distinct physical demands. Their roles within the symphony orchestra also vary. This article explores those differences to help you make the right choice.
Members of the bowed string instrument family
The violin and viola belong to the bowed string instrument family, alongside the cello and double bass.
Despite their differences, the violin and viola have much in common. These similarities reflect their close relationship.
Violin and viola: obvious similarities
Both are played on the shoulder in a similar position. Each also has four strings with which to produce music.
Their shape and use are similar as well. The musician uses a bow to make their strings vibrate.
Playing posture, number of strings, and overall shape
The way they are held, the number of strings, and even their overall appearance are similar. These characteristics show just how closely related the violin and viola are.
Differences in size and weight
Size is the main characteristic that distinguishes the violin from the viola. A violin has a body measuring approximately 35.5 cm, while a viola measures between 38 and 43 cm. They also differ in weight. A viola is generally bulkier than a violin. For example, a viola can weigh up to 550 g, whereas a violin weighs around 460 g. This difference is due to their respective sizes.
Standard viola and violin dimensions
| Instrument | Size in cm | Size in inches | Approximate age of player |
|---|---|---|---|
| Violin | 22.5 (1/16), 35.5 (4/4) | — | 3–4 years (1/16), 11–13 years and older (4/4) |
| Viola | 28 (1/8), 40.5 (large 4/4) | 11″ (1/8), 16″ (large 4/4) | — |
| Cello | 28 (1/10), — (4/4) | — | 3–4 years (1/10), 12–13 years and older (4/4) |
| Double bass | — | — | 5–7 years (1/8), adult (4/4) |
Violin and viola sizes by category
Violins are classified by size: 1/16, 1/10, 1/2, 4/4, and so forth. Violas, meanwhile, range from 12″ (1/8) to 16.5″ for the largest models.
An intermediate model such as the Gliga Genial 1 7/8 violin is designed for smaller adults and teenagers. It offers a good compromise.
How instrument size relates to the player’s age
Before choosing a violin or viola, it is crucial to measure the player’s arm.
Choosing the wrong size can cause pain and technical difficulties, potentially hindering the musician’s comfort and progress.
The viola’s greater weight compared with the violin
Because the viola is larger, it is also heavier than the violin: 550 g compared with 460 g.

Finger spacing and dexterity
Violas are larger than violins, requiring wider finger spacing. This is due to the greater distance between the strings. A violist needs more dexterity to play.
The viola’s greater size influences finger spacing. Its more widely spaced strings require broader movements. This calls for considerable skill and good coordination.
Viola playing is distinguished by this wider finger spacing. Unlike the violinist, the violist must combine virtuosity with agility of the hand, mastering technical movements while pursuing artistic expression.
Range and string tuning
The violin and viola each have four strings, but they are not the same. Violin strings are tuned E–A–D–G, giving the instrument a higher sound. Viola strings are tuned A–D–G–C, producing a lower sound. This difference creates distinct tone colors. The viola produces dark, mellow tones, while the violin has a clearer, brighter sound.
Differences in string tuning
The instruments’ different tunings offer a variety of sounds. With its distinctive tuning, the viola expands the tonal possibilities. It can produce low notes that the violin cannot reach, enriching orchestral music with a deeper, fuller voice.
The viola’s low register and the violin’s high register
The arrangement of the strings distinguishes the violin from the viola. The violin excels in high notes thanks to its E–A–D–G tuning, while the viola, tuned A–D–G–C, covers more of the lower register. This configuration contributes to the harmony of string music. The viola provides a deep, melodious sound that contrasts with the violin.
Understanding the difference between the violin and the viola
Physical demands associated with size
The viola is larger than the violin and therefore more difficult to hold. Its longer strings require wider finger spacing, making movements less effortless.
The viola is also heavier, so the arm must work harder to support it.
Differences in bows and handling
A larger, heavier bow is used for the viola. This helps produce the desired deep tones, but it also makes bow control more complex. Playing the viola requires considerable skill.
Reading different clefs
Music reading differs as well. Violists read alto or treble clef, whereas violinists read treble clef. This difference requires players to adapt.
Place and role within orchestras
In symphony orchestras, the violin occupies a prominent place. It has a vast repertoire and often serves as the principal solo instrument. The viola plays a more varied role. It may double the violin, accompany it, or complete the harmony. Although its repertoire is smaller, the viola remains essential. It bridges the violins, cellos, and double basses. It is sometimes featured prominently, as in Berlioz’s symphony “Harold in Italy.”
The solo violin and its vast repertoire
The violin has an extensive repertoire. It can be heard as a solo instrument within the orchestra. Its clear tone and agility make it a natural choice for leading parts.
The viola’s more versatile, complementary role
The viola plays a more varied role. It may double the violin, accompany it, or complete the harmony. Although its repertoire is smaller, the viola is essential. It connects the orchestra’s different sections.

Distinct tone colors
The violin and viola also differ clearly in sound. The violin has a clear, bright sound thanks to its thinner strings and high register. By contrast, the viola offers a warmer, mellower sound because of its lower strings and larger body.
Each tone color plays a major role in the orchestra. Musicians choose these instruments for their distinctive sounds.

Conclusion
The violin and viola are bowed string instruments. They share many similarities, but they also have marked differences that make them complementary within an orchestra. These differences concern their size, weight, and sound. The violin has a clear, bright voice, while the viola has a warmer, gentler tone.
The choice between violin and viola depends on personal taste, both in terms of each instrument’s sound and its role in a symphony. Their differences and complementary qualities allow both instruments to bring something unique to the orchestra.
Violins and violas thus complement one another to create rich, beautiful orchestral music. Each has an important place in this harmony, illustrating how diversity can enrich our musical world.
