the pronunciations of music 1, 2, 3, 4, 5, 6 and 7 are do, re, mi, fa, sol, la and si.

in the notation, the notes are the symbols that record the level and length of the notes. The symbols used to indicate the level of these dominant sounds are marked with seven Arabic numerals.

They are written as:

1, 2, 3, 4, 5, 6, 7.

they are pronounced as:

do, re, mi, fa, sol, la, si (duo, lai, mi, fa, suo, la and Xi).

Notes are closely related to pitch, and there is no note without pitch.

Extended information:

The movable roll-call method is based on the relative pitch, and its roll-call is not fixed, taking the key as the criterion, and the singing of do, re, mi, fa, so, la and ti in major is fixed, such as do in C major and do in D major. Singing la, ti, do, re, mi, fa and sol in minor, such as singing la in A minor and singing la in B minor, etc.

China folk music also adopts fixed and movable roll names. In the Song Dynasty, both the Gongchi notation and the folk character notation were recorded by fixed roll-call method. The music scores used by Xi 'an Drum Music, an ancient folk music, which is preserved today, are the inheritance and development of the folk character spectrum in the Song Dynasty, and also belong to the fixed roll-call system.

all kinds of sound spectra are only expressed in different forms. A tone will have different notes in different music spectra, and it can be sung as a different "roll call" in different populations, but the only tone you want to sing is this one.
