Which term describes a scale that moves from lower to higher pitches?

The term that describes a scale moving from lower to higher pitches is the ascending scale. An ascending scale consists of a sequence of notes where each successive note is higher in pitch than the previous one. This movement creates a sense of rising or upward motion in the music, which can evoke feelings of excitement or anticipation.

The concept of ascending scales is fundamental in music, as it is often used in various genres to create melodies and harmonies that lead towards a climax or a higher point in the composition. This contrasts with descending scales, where the notes move from higher to lower pitches, creating a different emotional effect.

While harmonic and chromatic scales have their own specific definitions related to harmonization and intervals, respectively, they do not solely describe the action of moving upward in pitch like an ascending scale does.
