Triad

     A triad is a group of three notes having a specific construction and relationship to one another. They are constructed on 3 consecutive lines or three consecutive spaces. Each member of the triad is separated by an interval of a third. The triad is composed of a Root, Third, and Fifth.

A staff is made up of five horizontal lines and four spaces.

Pitches are named after the first seven letters of the alphabet (A B C D E F G).

Speed (Tempo)

There are 15 major and 15 minor key signatures. The sharps or flats at the beginning of the staff indicate the main tone (diatonic) to which other tones are related.

There are many different types of scales. They are the backbone of music.

A major scale is a series of 8 consecutive notes that use the following pattern of half and whole steps:

An interval is the distance between two notes. Intervals are always counted from the lower note to the higher one, with the lower note being counted as one. Intervals come in different qualities and size. If the notes are sounded successively, it is a melodic interval. If sounded simultaneously, then it is a harmonic interval.
