The standard tuning frequency for each guitar string is as follows:
- E2: 82.41 Hz
- A2: 110 Hz
- D3: 146.83 Hz
- G3: 196 Hz
- B3: 246.94 Hz
- E4: 329.63 Hz
These frequencies are based on the equal-tempered tuning system, which is the most common tuning system used in Western music. In equal-tempered tuning, the intervals between the notes are evenly spaced, which makes it easy to play music in different keys.
There are a number of factors that can affect the frequency of a guitar string, including the length, tension, and thickness of the string. The longer and thinner a string is, the lower its frequency will be. The thicker and tighter a string is, the higher its frequency will be.
Guitarists often tune their guitars to other frequencies, depending on the genre of music they are playing or the effect they want to achieve. For example, metal guitarists often tune their guitars down to A432 or even lower to get a heavier sound. Jazz guitarists sometimes tune their guitars up to A442 or higher to get a brighter sound.
Here are some examples of different guitar tunings:
- Standard tuning: E2 A2 D3 G3 B3 E4
- Drop D: D2 A2 D3 G3 B3 E4
- Drop C: C2 G2 C3 G3 B3 E4
- DADGAD: D2 A2 D3 G3 A3 D4
- Open G: D2 G2 B2 D3 G3 B3
Guitarists can also use tuners to tune their guitars to specific frequencies. This is useful for playing with other musicians who are tuned to a different frequency or for recording music in a different tuning.
No matter which tuning you choose, it is important to tune your guitar regularly to keep it sounding its best.
