# 音樂理論：與彈奏吉他音符有關的頻率

EDIT4: Thanks for the responses. I understand that some issues could be around the guitar, recording instrument, and even the recording room. However, the important question is - In case of a guitar, what is a realistic (or most probable) relationship between a fundamental and its harmonics? (assuming a normal scenario, similar to when we hear someone play). I need to come up with the most probable mathematical relationship.

EDIT: Another sample for E2 string pluck (after properly checking the tuning and ensuring no other string vibrates):

EDIT2: Sample for E2 when the string is plucked close to the center instead of near the bridge:

EDIT3: Sample for E4 (330 Hz - top most string) has highs at second and third harmonic. Sample for B open string (250 Hz):

## 最佳答案

    N:     1  2  3   4  5   6   7   8    9   10   11     12
Note:  E2 E3 B3  E4 G#4 B4 (D4) E5   D5  G#5  (n/a)   B5   ...

N; ratio of harmonic's frequency to the fundamental frequency
7th harmonic is pretty badly tuned in equal temperament, 11th is very badly so.
