Just like people have names, each note level in music also has its own name, which is the "note name". Sound names have different names in different countries, and they are roughly divided into two types: the German and Austrian sound name systems and the British and American sound name systems. Roll call is the name people use when singing music scores. Commonly used solfa methods include first-key solfa and fixed-key solfa. The sound name is the name of the sound, and it will not change anywhere. It is inherent to each sound and belongs to that sound; while the roll call is a name used by people when singing music scores, and it is based on the sound. Differences due to changes in pitch or pitch.

What are the basic sound levels of sound names?

In the musical sound system, seven sound levels with independent names are called basic sound levels (also called natural sound levels). The basic sound level is represented by the seven letters "C, D, E, F, G, A, B", which is the "note name" of the basic sound level.

The German sound name system uses seven sound names: "C, D, E, F, G, A, H". H is used to represent the B sound in the British and American systems, and Use "B" to represent the sound bB in the British and American systems.

In the musical sound system, there are only these seven note names, and the names of other note levels are just recycled or varied uses of these seven note names, which can be clearly seen on the piano keyboard. The notes on the keys are the basic pitch levels.

Solfa

When singing a score, it is usually a solfa at the singing level, namely: do, re, mi, fa, sol, la, si , these seven roll calls. However, when using the staff, the key signature of the music score must be taken into consideration, and the solfa method must be used.

The commonly used solfa methods include the first-key solfa method and the fixed-key solfa method.

The first-key solfa method means that the main note of the key is sung as "do", and the other notes are sung according to the corresponding pitch relationship. It is a solfa method based on relative pitches. . When the key changes, you only need to find the tonic of the key without adding temporary rising and falling marks.

For example, in the key of F, the F sound is sung as "do", the G sound is sung as "re", the A sound is sung as "mi", the bB sound is sung as "fa", and the C sound is sung as "fa". It is sung as "sol", the D sound is sung as "la", and the E sound is sung as "si".

The so-called fixed-key solfa method refers to: no matter what key the music score is, C is sung as "do", that is, the solfa method is based on absolute pitch. When the key changes, the pitch level should be sung a semitone higher or lower accordingly, but the roll call remains the same.

For example: No matter it is the key of F, #F, bF, or any other key, as long as it encounters the C sound, it does not matter whether it is #C, bC, ×C, bbC, it will be the same. All are sung as "do". Data expansion

Octave?

According to the order of basic tone levels, starting from a certain tone level, from high to low or from low to high, counting to the eighth tone , then the relationship between these two sound levels is octave, and the accurate name should be "pure octave".

In other words, from a certain sound level (regardless of basic sound level or modified sound level) to the adjacent sound level above or below it with the same name, then the relationship between the two sound levels is a pure eight Spend. Two tones in a pure octave relationship have the same meaning in music, just different pitches.
