An interval is a word musicians use to describe the distance between two notes. Being able to identify intervals is an important skill for musicians and helps not only with reading music, but crucially with working out melodies by ear. This is a vital skill, particularly within pop music styles.
Firstly Listen to the Relationship Between the Notes
When you hear two notes played after each other, pay close attention to the relationship between them. Does the second note sound higher or lower than the first? Does it sound close or far apart? Does the combination sound happy or melancholic? Making these basic observations will help you narrow down the interval in question.

Bonus Tip: Use a Piano or Keyboard
A piano keyboard is a great visual reference for intervals. Play the two notes and observe the distance between them on the keyboard. Count the semitones between the notes to identify the interval. With consistent practice, you will memorise these sounds.
