Basic music theory knowledge for guitar

Classical guitar uses five-line notation. ; A tone name is the name of a tone, and its reading is the sung name of that tone. This is the pitch of C major.

A small dot above the basic symbol indicates that the tone is voiced one group higher. Adding a dot below the basic symbol lowers the pitch by one tone group. And so on, adding two dots means raising or lowering the sound by two groups.

The distance between two tones is called an interval, and is measured in degrees. 1-1 is a degree, 1-2 is a second degree, and so on. 1-5 is a fifth, 1-6 is a sixth, and 1-7 is a seventh. The division of the tones within an octave into twelve tones of equal frequency is called the twelve equal temperament.

The semitone is the smallest unit of the twelve tones of equal temperament, and two semitones make a whole tone. Except for 3-4 and 7 to the high 1, which are semitones, the others are whole-tone relationships. The following notation variations are also possible: the # ascending sign means to raise the note by a semitone; the b descending sign means to lower the note by a semitone; the x regaining sign means to raise the note by two semitones; the bb regaining sign means to lower the note by two semitones; and the ヰ restoring sign means to restore the note.

If a note in the same measure doesn't touch the restoration mark, it is always the same as the original note, whether raised or lowered. That is to say, the variation mark is effective in one measure, to the next measure will not work, in the measure called temporary variation mark, in the treble clef followed by the key number.

Timing of tones: The short horizontal lines added after a tone are called time increment lines. Each additional line represents an increase of one beat.
