To determine the type of interval you hear in an audio sample, you would need to listen to it carefully. However, I can help you understand the differences between the intervals you've mentioned:
-
Harmonic Second: This is an interval made by playing two notes simultaneously that are adjacent in pitch. It typically sounds quite close together.
-
Harmonic Third: Two notes played together that are four semitones apart. This interval sounds consonant and pleasant.
-
Melodic Third: This interval occurs when two notes that are four semitones apart are played in sequence (one after the other), rather than simultaneously.
-
Melodic Fifth: This interval consists of two notes that are seven semitones apart and sounds quite consonant but spaced at a greater distance.
To identify the interval you are hearing, consider the distance between the two notes you perceive, and whether they are played simultaneously (harmonic) or in sequence (melodic). Listening closely to their qualities will help you classify the interval correctly.
