At the request of netizens, let’s write about the conversion relationship between music scores and data in detail below.

The first two sections of "Farewell" by Master Li Shutong will be used to illustrate the conversion method.

The lyrics of this part are: "Outside the long pavilion, beside the ancient road,";

The music score of this part is: | 5 35 1 - | 6 16 5 - |.

(Note: 1 in the score is the treble, with a dot above it; there are also some notes that should be underlined, but they cannot be marked here. Interested netizens should check the official music score.)

Then, based on this, the data table for the first two sections of "Farewell" can be written:

//---------------- -----------------------*/

//code unsigned char sszymmh[] = {

// 5, 2, 2, 3, 2, 1, 5, 2, 1, 1, 3, 4,

//Sound, alto, 2 and a half beats; Micro, alto, 1 beat Half a beat; Sui, alto, 1 and a half beats; Duo, treble, 4 and a half beats

//6, 2, 2, 1, 3, 1, 6, 2, 1, 5, 2, 4,

//La, alto, 2 and a half beats; Duo, treble, 1 and a half beats; La, alto, 1 and a half beats; Sui, alto, 4 and a half beats Shoot

//0, 0, 0};

//End mark

/*------------- -----------------------

Remember: a group of three numbers represents a note.

The first number is one of 1234567, which represents the note Dole Mi Fa...;

The second number is one of 0123, which represents bass, alto, treble, Super treble;

The third number is the number of half beats, representing the length of time.

When all three numbers are 0, it represents the end of the music data table.

Use this data table to replace the data table of "Only Mother is Good in the World" in the program, and this program can play the first two sections of "Farewell".
