What do c and f mean? How many tones are there altogether? What do you mean, respectively?

C is a phonetic name, and F is also a phonetic name. C is the key to sing DO with c, and f is the key to sing DO with f. So when singing, some people rap and sing C and F. That is, the scale of C and the scale of F. For example, the melody of C is 1 155, which is the four tones of CCGG. The melody of F key is 1 155, which is the four ones of FFCC. Note that this c is an octave higher than C.

Seven notes in natural major? A *** 15 tone, three of which are homophones, so listening with ears is 12 tone and writing is 15 tone.

CDEFGAB in music is a scale.

The most widely used octave, its interval organization is that there are five whole tones within each octave, which are divided into two strings and three strings, and the two strings are separated by semitones.

Popular in Southeast Asia. Its interval organization is to divide an octave into seven roughly equal intervals, each of which is smaller than the whole tone but larger than the semitone.

C major is a smooth and moderate white tonality, as quiet and sunny as a valley, which is more quiet and solemn than ordinary major (such as Bach's prelude to C major). In classical times, C major was a special mode for royal celebrations and VIP invitations (such as Haydn's Symphony No.97 in C major and Mozart's Symphony No.41in C major). Later, C major was often regarded by musicians as returning to nature, pursuing rationality or looking forward to the future.

The parallel minor in C major is a minor, and its sounds are arranged like this:

Let's distinguish major and minor in this way. The first three notes are major scales with major intervals, and the first three notes are minor scales with minor intervals. The constituent sounds of the parallel minor are the same as those of the major, that is, the parallel minor begins with the sound of major 6.

The juxtaposition of C major is A minor, D major is B minor, and G major is E minor. This is a relationship diagram, so that we can distinguish the major and minor of a song.

Major tunes are often clear and magnificent; Minor is often gentle and lyrical. On chords, C chords are used at the beginning and end of songs in C major. Songs in minor begin and end with chords. The songs in C major are mainly C, G and F, and the songs in A minor are mainly Am, Em and Dm.

F natural major is a major based on F sound, which consists of F, G, A,? B, C, D, E and F, and key signature has a flat sign. The relative minor is D minor and the parallel minor is F minor. Major is characterized by the formation of a major third degree relationship between the first sound and the third sound.

Key signature in F major is obtained by lowering the B note in the third line of the staff by two degrees.
