Measuring a viola accurately is crucial for several reasons. Whether you're a player looking for the perfect instrument, a luthier crafting a new viola, or simply curious about its dimensions, understanding the different measurements and how to take them is essential. This guide will walk you through the process, covering everything from body length to string length.
What are the Key Measurements of a Viola?
Several key measurements define a viola's size and playing characteristics. These include:
- Body Length: This is the overall length of the viola's body, measured from the top bout (the upper curved section) to the bottom bout (the lower curved section). This is often the primary measurement used to categorize viola sizes.
- String Length (Vibrating Length): This measures the distance between the bridge and the nut, determining the pitch and tone of the instrument.
- Upper Bout Length: The width of the viola at its widest point near the scroll.
- Lower Bout Length: The width of the viola at its widest point near the bottom.
- C-Bout Length: The width at the point where the C-string would be positioned.
- Overall Length: This includes the body length plus the length of the neck and pegbox.
How to Measure a Viola's Body Length
Measuring the body length is straightforward:
- Lay the viola flat: Place the viola on a flat, stable surface.
- Use a ruler or measuring tape: A flexible measuring tape is ideal for following the curves accurately.
- Measure from top bout to bottom bout: Carefully measure the distance from the highest point of the top bout to the highest point of the bottom bout, following the curve of the instrument. Make sure the measuring tape is snug against the surface of the viola. Record the measurement in centimeters or inches.
How to Measure a Viola's String Length
Measuring string length requires slightly more precision:
- Use a ruler or measuring tape: Again, a flexible tape measure is best.
- Measure from nut to bridge: Place the zero mark of your measuring tape precisely at the nut (the small piece of wood at the end of the fingerboard where the strings begin). Extend the tape to the bridge (the curved piece of wood that the strings rest on). Measure along the strings themselves, not the fingerboard. Record the measurement. Note that the bridge's position can slightly affect the string length.
What are the Standard Viola Sizes?
Viola sizes are often categorized by their body length. While there's no strict standard, common sizes include:
- 14 inch: This is often considered a smaller viola, suitable for younger players or those with smaller hands.
- 15 inch: A common size for intermediate players.
- 15.5 inch: A popular size for advanced players.
- 16 inch: A larger size often preferred by professional players.
- 17 inch: Often considered a very large viola.
Keep in mind that these are approximations, and the specific dimensions of a viola can vary slightly even within these size categories.
Why is Measuring a Viola Important?
Accurate measurements are crucial for several reasons:
- Selecting the right viola: Knowing your size helps in selecting a suitable instrument. Too large, and the viola will be difficult to play; too small, and it may lack resonance and projection.
- Viola maintenance and repair: Measurements are essential for luthiers making repairs or modifications to a viola.
- Comparing instruments: Measurements allow you to compare different violas objectively.
- Assessing the instrument's condition: Changes in measurements can indicate warping or other problems requiring attention.
What tools are needed to accurately measure a viola?
You primarily need a flexible tape measure and possibly a ruler for more precise measurements of smaller parts. A sharp pencil and notepad for recording your measurements are also helpful.
By following these steps, you can accurately measure your viola and gain a better understanding of its dimensions. Remember to always handle your instrument with care.
