What is minor third?

A minor third is a musical interval that spans three half steps or semitones. It is equal to three half steps on a piano keyboard.

In terms of frequency ratio, a minor third is characterized by a ratio of 6:5. This means that the higher note is vibrating at a frequency that is 6/5 times the frequency of the lower note.

Minor thirds are commonly found in music and are considered to have a melancholic or sad quality compared to major thirds. They are often used in harmonies and chord progressions to create tension or dissonance that can then be resolved.

Some examples of familiar musical intervals that are minor thirds include the opening notes of the song "Greensleeves" and the first two notes of "Smoke on the Water" by Deep Purple.

Overall, minor thirds play an important role in music theory and are essential building blocks for creating harmonies, melodies, and chord progressions.
