Learn the concept of intervals and their use in music theory.
Interval refers to the pitch difference between two notes. It is a concept used in music to describe the distance between notes. Intervals can be represented by numbers or interval names.
The size of intervals can be determined by the number of semitones. Halftone is the smallest unit of pitch in music, such as the pitch difference from C to C # or from E to F, which is a half tone.
In Western music, there are several commonly used intervals: Half step: The minimum interval between two adjacent notes, which is one half tone. Whole step: The interval between two adjacent notes, i.e. two semitones. Major second: Two whole notes or four semitones separated between two notes. Minor second: Two notes separated by a whole or two semitones. Major third: Two notes separated by two whole notes and one half note, or four half notes. Minor third: Two notes separated by a whole note and two semitones, or three semitones.
In addition to the common intervals mentioned above, there are also larger and smaller intervals, such as fourth, fifth, sixth, seventh, etc. Each interval has its unique timbre and emotional characteristics, playing an important role in the expression of music.
