Changing Pitch
* Fretting: The most fundamental way to change pitch on a guitar is by pressing down on the strings at different points along the fretboard. This shortens the vibrating length of the string, making it higher in pitch.
* Tuning Pegs: These are located at the headstock of the guitar. By turning them, you adjust the tension of the strings, which directly affects their pitch. Tightening the strings raises the pitch, while loosening them lowers it.
* Capo: A capo is a device that clamps down on all the strings at a specific fret. This effectively changes the "nut" of the guitar, raising the pitch of every note played.
Changing Frequency
* Vibrato: This involves rapidly and subtly adjusting the pitch of a note by slightly bending the string while it's being held down. This creates a wavering effect, often used for expressive purposes.
* Bending: Bending a string involves pressing it down and then pulling it up with your finger, increasing the tension and raising the pitch. This is commonly used to achieve a "blues" sound.
* Harmonics: These are produced by lightly touching a string at a specific point while plucking or strumming it. This creates a higher-pitched overtone, which can add a unique quality to the sound.
Relationship Between Pitch and Frequency
It's important to understand that pitch and frequency are directly related. Higher pitch means higher frequency, and lower pitch means lower frequency. When you change the pitch of a note on a guitar, you are also changing the frequency of the sound waves it produces.
