A scale is a series of notes arranged in ascending or descending pitch.

Explanation:

A scale is a sequence of sounds that follows a pattern using tones and semitones to form a cycle that repeats in both the acute and bass direction. When sung or played from bass to treble we say that it is in ascending form where it will restart its cycle 1 octave higher, otherwise downwards re-starting its cycle an octave lower.
