Understanding the Viola’s Strings and Their Standard Tunings
The Four Strings: The viola has four strings, namely the C string, G string, D string, and A string. Each string has a specific pitch it should be tuned to. The C string is the thickest and produces the lowest pitch, while the A string is the thinnest and has the highest pitch. For example, the C string is tuned to a frequency of around 65.41 Hz, the G string to about 98 Hz, the D string to approximately 146.83 Hz, and the A string to 220 Hz. Understanding these standard frequencies helps you know when your strings are in tune.
Tuning Order: It is generally recommended to tune the strings in a particular order. Starting with the A string is a common practice. This is because the A string is often used as a reference pitch. Once the A string is tuned, you can then tune the other strings relative to it. For instance, you can tune the D string by playing the fifth fret on the A string, which should produce the same pitch as the open D string.
Using a Tuner: A Reliable Tool for Precision
Types of Tuners: There are various types of tuners available. Electronic tuners are popular as they provide accurate readings. They can be clip-on tuners that attach to the viola’s pegbox or handheld tuners. Smartphone apps also function as tuners. For example, a clip-on tuner senses the vibration of the string and displays the pitch on a screen. It shows whether the string is sharp (higher than the correct pitch), flat (lower than the correct pitch), or in tune.
How to Use a Tuner: To use an electronic tuner, turn it on and select the viola or string instrument mode if available. Pluck the string you want to tune. The tuner will detect the pitch and indicate if it needs adjustment. If the pitch is sharp, you need to loosen the string by turning the peg counterclockwise. If it is flat, tighten the string by turning the peg clockwise until the tuner shows that the string is in tune.
Tuning by Ear: Developing a Musical Ear
The Fifth Fret Method: One way to tune by ear is using the fifth fret method. As mentioned earlier, playing the fifth fret on the A string gives the pitch of the D string. Similarly, the fifth fret on the D string gives the pitch of the G string, and the fourth fret on the G string gives the pitch of the C string. For example, when tuning the D string, play the fifth fret on the A string and then adjust the D string until both pitches match. Listen carefully for any differences in pitch and make small adjustments until they sound the same.
Harmonics Method: Another ear-tuning technique is using harmonics. Play the harmonic at the twelfth fret on the A string and then play the harmonic at the seventh fret on the D string. These two harmonics should produce the same pitch. If not, adjust the D string accordingly. This method requires a more refined ear but can be very effective in achieving accurate tuning.
Common Tuning Problems and How to Solve Them
String Slipping: Sometimes, the strings may slip out of tune easily. This could be due to a loose peg or worn-out string. If the peg is loose, you can apply a small amount of peg compound or chalk to the peg to increase friction. For a worn-out string, it is advisable to replace it. For example, if you notice that the A string keeps going out of tune, check if the peg is loose. If so, apply a bit of peg compound and then retune the string.
Intonation Issues: Even after tuning, you may experience intonation problems while playing. This could be because of improper finger placement or a poorly adjusted bridge. Check your finger placement to ensure you are pressing the strings in the correct positions. If the bridge is the issue, it may need to be adjusted by a professional luthier. For instance, if you find that certain notes on the G string are always out of tune, it might be worth having a luthier look at the bridge to see if it needs any adjustments.
Maintenance and Regular Tuning Checks
Environmental Factors: The viola is sensitive to changes in temperature and humidity. Extreme changes can cause the strings and the instrument itself to expand or contract, affecting tuning. Store your viola in a case in a stable environment, away from direct sunlight, heaters, or damp areas. For example, if you take your viola from a cold outdoor environment into a warm room, it is advisable to let it acclimate for a while before tuning.
Regular Tuning: Make it a habit to tune your viola regularly. Even if you haven’t played it for a short while, the strings may have gone out of tune. Tuning before each practice session or performance ensures that you are always playing in tune. This regular practice also helps you become more proficient in tuning and more sensitive to any tuning issues.
