I’m unable to listen to audio samples or click play buttons. However, I can help you understand the types of intervals!
- A harmonic second is when two notes played simultaneously are a whole step apart.
- A harmonic fifth is when two notes played together are seven half steps apart.
- A melodic third is when two notes are played one after the other and are four half steps apart (a significant third in terms of melody).
- A melodic fifth is similar but spans seven half steps when played in sequence.
If you can describe the notes or the sound, I can help you determine the type of interval!
