Understanding A440 and EADGBE Guitar Tunings: The Musical Reference
The world of music, especially guitar playing, is rich with various tunings that can alter the sound and feel of a piece entirely. Two common tunings that often come up in discussions are A440 and EADGBE. Let's delve into what these tunings mean and how they are used in the realm of guitar music.
A440: The Standard Reference for Tuning
A440 Hertz (Hz) is a frequency that is commonly used as the tuning reference for musicians. It is the standard pitch for the note 'A' above middle C. This frequency is standardized by the International Organization for Standardization as ISO 16. When a guitarist tunes their A string to A440, it ensures that all the other strings are in relative tune, creating a harmonious and consistent sound across the instrument and with other instruments in a musical setting.
Therefore, A440 is not a separate tuning but a frequency reference point. All the guitar strings are calculated in relation to this pitch. For instance, the E strings (two E strings on a guitar) are tuned to the E note, which is below the A440 but in relative tune. An electronic tuner takes care of this for you, ensuring that your guitar is in tune with A440, which is the standard tuning for most musical instruments.
While A440 is the most commonly used reference, some guitarists, such as Rick Derringer, might use a slightly different tuning reference. However, these slight deviations are minimal and do not significantly affect the overall tuning harmonic consistency when playing with musicians using A440 as their tuning reference.
EADGBE: The Most Common Tuning in Western Music
EADGBE refers to the standard tuning for a six-string guitar. Each string, from the top to the bottom, is tuned to the following notes: E, A, D, G, B, and E. This tuning is commonly known as standard tuning or concert tuning and is used extensively in Western music. The tuning is derived from the A440 reference point, with each string tuned in relative intervals to the A440 pitch.
It is not unusual for guitarists to tune their instruments down, for example, to a half step below the standard tuning. This would mean that the two E strings would be lowered to Eb, creating an Eb tuning. Notable guitar players such as Jimi Hendrix and Stevie Ray Vaughan favored this tuning, known as the 'slippery finger tuning,' which allows for a different sound and feel to the guitar.
Alternative Tunings and the Need for Consistency
While A440 and EADGBE are the most common, there are other alternative tunings used in guitar music, such as DADGAD. However, EADGBE remains the most prevalent and is favored by many musicians for its versatility and the familiar sound it provides. Consistency in tuning is crucial for musicians, as deviating too much from A440 can result in a sound that may not be harmonious with other instruments and can even sound like 'freeform jazz.'
Electronic tuners are widely used and set by default to A440. If you want to explore other tunings, you can adjust your tuner, but unless you are a['']
guitarist who specifically requires a different tuning for a particular song or style, A440 and EADGBE are the most practical and universally accepted tuning options in the guitar world.
In conclusion, A440 serves as the standard reference pitch for all instruments, ensuring consistency, while EADGBE is the most common guitar tuning for Western music. Whether you are a beginner or a seasoned guitarist, understanding these tunings and how they work together can greatly enhance your playing and listening experience in the vast landscape of music.
