Scale:-

A succession of single notes, lying within an octave, the notes arranged in order of pitch, moving upwards or downwards. There are many different kinds of scale on which music can be based. Western music has largely been based on two main kinds of scale: Major, and Minor.

The characteristic sound of any scale is determined by its number of steps, these steps known as Intervals. An interval is the distance, or difference in pitch between two notes. The notes may be sounded simultaneously, making a “Harmonic Interval”; or they may be sounded one after another, as in a Melody, making a “Melodic interval”.

All scales are simply subsets of the chromatic scale. Most scales have 7 different notes, although some have 5, 6, or 8. The simplest scale, which will be used as an example for the discussion of chords, is the C major scale, which is "C, D, E, F, G, A, B". A major scale is defined by the intervals between these notes: "(T T S T T T S)", where "T" indicates Tones (whole step) and "S" indicates Semitones (half steps).

Example:-

Chromatic Scale is…..

C      C#    D      D#    E      F      F#    G      G#    A      A#    B      C.

Tone - Next to next.

Semitones - Just Next.

Major Scale Interval Is:-

T      T      S      T     T     T     S.

To memorize, it is Double T S, Triple T S.

Minor Scale Interval Is:-

T      S       T      T      S       T      T.

To memorize, it is T S T - T S T - T.

There are three types of scale category.

1.     Chromatic,

2.    Diatonic, and

3.    Synthetic.

Different kind of scales:-

Major Scale Modes, Melodic Minor Modes, Symmetric Scales, Pentatonic Scales, Blues Scales, Bebop Scales, Harmonic Scales, Exotic Scales, and Miscellaneous.
