Music has been an essential part of human culture for centuries. One of the most beloved musical instruments is the guitar, specifically, the acoustic guitar. Its sound has been the inspiration for countless musicians and songwriters around the world. But have you ever wondered if an acoustic guitar changes its sound over time? The answer, in short, is yes. An acoustic guitar can change its sound over time due to various factors such as weather, humidity and age.
In this blog post, we’ll delve into the details of these factors and how they can alter the sound of an acoustic guitar. We’ll also discuss the best type of wood suited for acoustic guitar sound. So without further ado, let’s jump right in!
Weather can impact the sound of an acoustic guitar
The weather can significantly impact the sound of an acoustic guitar. Changes in humidity and temperature can cause the wood to expand or contract, resulting in changes in the guitar’s resonance. As the wood of the guitar expands or contracts, the tension on the strings also changes, leading to variations in the guitar’s pitch.
For example, if you leave your guitar in a hot and dry room, the wood can contract, causing the bridge to sink and pulls the strings tighter, raising the guitar’s pitch. Conversely, if you leave your guitar in a cold and damp room, the wood can expand, causing the bridge to rise, which reduces the string tension, leading to a lower pitch.
The changes in humidity and temperature can also affect the guitar’s durability. Extreme heat and cold can cause the wood to crack or split, damaging the guitar’s sound quality. Therefore, it’s essential to store your guitar in a safe and regulated environment.
Humidity plays a significant role in the sound of an acoustic guitar
Humidity is another major factor that affects the sound of an acoustic guitar. When the relative humidity in the air changes, the wood absorbs or releases moisture, leading to variations in the guitar’s sound. The optimal range of relative humidity for guitar sound is between 45% to 55%. If the humidity level exceeds this range, it can cause the guitar’s soundboard to bulge or warp, leading to a lousy sound.
For instance, if you live in a climate that experiences extreme humidity, it can cause the guitar’s soundboard to expand, resulting in a bulge that pushes the bridge up, altering the guitar’s action or string height. Conversely, if you live in a dry climate, it can cause the guitar to crack or split, leading to permanent damage.
Therefore, it’s essential to store your guitar in a room with a controlled temperature and humidity. A dehumidifier or a humidifier can help maintain the optimal humidity level for your guitar.
The age of the guitar can also impact its sound
The age of the guitar can also impact its sound. As a guitar ages, the wood becomes denser, causing the sound to mature and become richer. The more the guitar is played, the more its sound develops, leading to a unique tone that cannot be replicated by any other guitar.
Moreover, as the guitar ages, its tonewoods dry out, which can cause the guitar’s sound to become boomy or muddy. Therefore, it’s crucial to keep the guitar hydrated by using a guitar humidifier to maintain the optimal humidity level.
The type of wood used in the guitar’s construction affects its sound
The type of wood used in the construction of an acoustic guitar plays a crucial role in the guitar’s sound quality. The type of wood affects the guitar’s tone, sustain, and projection. Let’s take a closer look at some of the best tonewoods used for acoustic guitar construction.
1- Sitka Spruce:
Sitka Spruce is one of the most popular tonewoods used in acoustic guitar construction. It has excellent strength-to-weight ratio, which provides a bright, crisp tone with excellent projection. It is used for guitar soundboard, providing a balance of volume, clarity, and sustain.
2- Rosewood:
Rosewood is another popular tonewood for acoustic guitar construction. It offers a rich, warm tone, with great sustain and depth. It is usually used for the back and sides of the guitar, providing a balanced tone with excellent projection.
3- Mahogany:
Mahogany is a dense tonewood that offers a warm, balanced tone, with excellent sustain and projection. It is typically used for the back and sides of the guitar, providing a strong midrange and crisp highs.
4- Maple:
Maple is a dense, hard tonewood that offers a bright, tight tone, with excellent sustain and projection. It is used for guitar necks, providing a fast, responsive feel, and intricate playing.
5- Cedar:
Cedar is a soft, lightweight tonewood that provides a warm, mellow tone with less projection. It is usually used for soundboards, providing a rich, complex tone with a quick response.
In conclusion, an acoustic guitar can change its sound over time, affected by weather, humidity, and age. The best type of wood suited for an acoustic guitar sound is subjective, depending on personal preferences, playing style, and musical genre. However, Sitka Spruce, Rosewood, Mahogany, Maple, and Cedar are some of the best tonewoods with unique properties that dictate the guitar’s sound quality.
If you own an acoustic guitar, it’s essential to take care of it properly, protecting it from the changing temperature and humidity to ensure its longevity and optimum sound quality. By doing so, you can enjoy your guitar’s beautiful sound for a lifetime.
