What is the scale? What is octave? What is "degree"?

A scale refers to arranging the tones in a mode in a step-by-step manner from the beginning to the end, from low to high, or from high to low. Octave refers to the eight tones of 1234567 1, which is a pure octave. Degree means that the relationship between 1 and the next 1 is a pure octave.

Scale is a form of mode, and its full name is mode scale. A scale must be a mode, and a mode is not necessarily a scale. Mode is the melody we hear when listening to songs, and scale is also a kind of melody.

Scales can be divided into natural seven-tone scale, pentatonic scale, gypsy scale, Arabic scale, six-tone scale, diatonic scale, chromatic scale and so on, which are composed of different scales.

Extended data meaning:

The specification of the interval relationship between sounds in a sound sequence can be used to refer to a sound sequence. Each tone in the scale can be used as the tonic to establish the mode, which can form seven different seven-tone natural modes. All scales with averaging tendency, when different tones are selected as tonic in the same scale, the modes are similar and can no longer be divided into different modes, but the pitch of tonic can be different.

Scale professional classification:

The natural major of the scale is basically "full half full half" and the natural minor is "full half full half full half".
