Respuesta :
In music theory, a scale is any set of musical notes ordered by fundamental frequency or pitch. A scale ordered by increasing pitch is an ascending scale, and a scale ordered by decreasing pitch is a descending scale. Some scales contain different pitches when ascending than when descending, for example, the melodic minor scale.
Answer:
There are many reasons for this, including the fact that cultures develop musical scales independently. Scales are based on the harmonic series, but they differ in the notes that are used and how many there are in an octave. For example, may folk scales are pentatonic — they have only five notes in an octave.
