Sound |
To understand stringed instruments (or any type) you must first understand the concepts of sound. Sound is produced by vibrations from objects that create certain (compression) waves that travle through the air. Differences in these vibrations create different sound waves. Each of these waves has a different frequency, or rate at which it vibrates. Here is a list of terms that may be helpful:
Pitch- what we perseve as high notes and low notes are seperate pitches. The higher the frequency the higher the pitch.
Amplitude- The higher the amplitude pf the sound wave, the louder we hear it.
Hertz- a unit of measurement used to measure the frequency. Equal to 1/s (s=seconds).
Harmonics- A series of musical notes whose frequencies are whole number multiples of the frequency of the fundamental tone, which is the lowest frequency able to be produced by an object such as an instrument. The first harmonic is that low note.
Natural frequency-(a.k.a fundamental frequency) the frequency at which an object vibrates when caused to vibrate by hitting, plucking, or any other type of diturbance.
Resonance - One object vibrating at the same natural frequency of another object causes that other object to vibrate. This usually makes us perseve that note as louder.
