How Do You Measure a Viola?
Measuring a viola involves several key dimensions, each crucial for assessing its playability, sound quality, and overall value. Unlike a simple length measurement, understanding a viola's dimensions requires a nuanced approach. This guide will walk you through the essential measurements and what they tell you about the instrument.
What are the standard measurements of a viola?
The standard measurements of a viola aren't rigidly defined like, say, the dimensions of a standard sheet of paper. However, there's a general range of sizes considered standard for different viola sizes, particularly for student and professional instruments. Key measurements include:
-
Body Length: This is the overall length of the viola's body, typically measured from the top bout (upper curve) to the bottom bout (lower curve). This is often the primary measurement used to categorize viola sizes (e.g., 15-inch viola, 16-inch viola). Sizes typically range from 14 inches for smaller student instruments to 17 inches or even larger for professional instruments.
-
String Length (Scale Length): This is the distance between the nut (where the strings start) and the bridge (where the strings vibrate). This is a critical measurement as it directly affects the pitch and tone of the instrument. Longer scale lengths generally produce deeper, richer tones.
-
Upper Bout Width: The width of the viola's body at its widest point near the scroll (the carved head).
-
Lower Bout Width: The width of the viola's body at its widest point near the bottom.
-
Rib Height (Depth): The depth or height of the viola's body. This, along with the width measurements, contributes to the overall volume and resonance of the instrument.
How do I measure a viola myself?
To measure your viola accurately, you'll need a flexible tape measure and a little patience. Here's a step-by-step guide:
- Body Length: Gently place the tape measure along the curve of the viola, from the top bout to the bottom bout, ensuring it follows the contour of the instrument.
- String Length (Scale Length): Measure from the nut (the ridge at the end of the fingerboard closest to the scroll) to the bridge (the piece of wood that supports the strings).
- Bout Widths: For both upper and lower bout widths, carefully position the tape measure across the widest points of the respective bouts.
- Rib Height: Measure the vertical distance from the top of the viola's body to the bottom at the center. This might require a bit of maneuvering, depending on the shape of the viola.
What do the viola measurements tell me?
Understanding these measurements can help you determine several things:
-
Suitability for the Player: Body length directly correlates with the size and comfort level for the player. A larger viola may be better suited for adults with larger hands, while a smaller viola is more appropriate for children or those with smaller hands.
-
Tone and Resonance: Larger violas generally possess deeper, richer tones due to increased resonance. However, the wood type, construction quality, and other factors significantly impact the final sound.
-
Instrument Value: While not the sole determining factor, the size and specific measurements of a viola can influence its overall value, particularly within the context of antique or historically significant instruments.
What about the other components of a viola?
While the measurements above focus on the viola's body, other aspects significantly contribute to its overall quality and playability. These include:
-
Wood Type: The type of wood used (such as spruce for the top and maple for the back and sides) heavily influences the instrument's tonal qualities.
-
Construction Quality: The craftsmanship and precision in the instrument's construction significantly affect its sound, playability, and longevity.
-
Set-up: This includes the bridge placement, string height (action), and the overall adjustment of the instrument to optimize comfort and sound.
By understanding these measurements and factors, you'll have a better appreciation for the nuanced world of viola making and selection. Remember, a skilled luthier or violin maker can provide the most accurate and comprehensive assessment of a viola's condition and quality.
