Practicing scales will provide you with the necessary skills to play different styles of music like Jazz, Flamenco or Blues. Musical scales are an essential part of music improvisation and composition. However, the distance between C and D, for example, is a full tone (or two semitones). For example, the distance between C and C# (black key next to C), or the distance between E and F (both being white keys). In other words, a semitone is also the distance between two consecutive keys on the piano. A semitone is the minimum distance between two consecutive notes in any tempered scale (12 equal semitones per octave). A scale is a set of musical notes ordered as a well-defined sequence of intervals (tones and semitones).
