Actually, it is the interval relationship between them. When the fifth partiality is e1, the pitch is C, and their interval is three degrees larger.

The common symbols of overtones are: harm., har., arm., ar., etc., and their ranges are indicated by dotted lines, with the number one higher than the left-handed fingering number indicating the grade, and with the number circled around it indicating the chord number. Among the overtones, octave overtones are used the most, so octave overtones can be represented by 8va, 8 (short for Otava) and oct. (short for octave).

overtone is a wonderful sound. The overtone played on the guitar is transparent and clear. Like a bell, it is also like a bell, and sometimes it is like a gurgling sound of running water or a monotonous dripping sound in a cave. In short, the occasional overtone in music is very interesting.

there are many ways to play overtones, which can be basically divided into Natural harmonics and Artificial harmonics.

Extended information:

Artificial overtones: Although natural overtones are easy to play, the overtones on the six strings and the six tuning notes of the guitar are very limited and difficult to continue, so it is impossible to play more and more complex overtones. However, artificial overtones greatly expand the number of overtones on the guitar, so that almost every tone on the guitar can find the corresponding overtones.

the pronunciation principle of artificial overtones is to press any non-empty chord tone on the guitar with your left hand, and then find the overtone point with this tone as the pitch, that is, the position away from the twelfth character of this tone, that is, 1/2 of the length of this chord. Just like playing natural overtones, touch the overtone point with your right finger, and pluck it as far away from the overtone point as possible with your right finger A (sometimes plucking the string with your right finger P).

when a refers to pronunciation and I refers to decisive departure from the string, it emits overtones that are eight octaves higher than the pitch. Playing artificial overtones, pressing the strings with your left hand, and beautifying the timbre if you can knead the strings. Artificial overtones are also often called octave overtones, because artificial overtones are mainly done by the right hand, so they are also called right-handed overtones. Artificial overtones are generally represented by 8va or ct, which means octave.
