Knowing interval names is useful. Being able to hear them lets you recognise and reproduce musical movement without counting keys. The goal is not to attach one permanent mood to each interval; register, instrument, rhythm, and harmony all affect the result.
This lesson gives you reference points for each interval using familiar melodies and easy-to-remember associations.
Song references
A familiar melody can give your ear a starting reference for an interval. These examples use the opening interval of each song; use them as memory aids, then listen for the same distances in other music.
Tap any row to hear the interval. Try singing the song reference in your head first, then listen to confirm.
Grouping by character
Rather than memorising all 12 at once, group them by how they feel.
Stable / open
Major intervals
Minor intervals
Tense / dissonant
How to practise
Ear training is a long game. A few minutes daily beats an hour once a week. Start with three rounds: choose P4 or P5 before tapping a reference, record your guess, and then repeat with M3 or m3. Only add a new pair after your guesses feel reliable.
Start with just two: Learn to tell P5 from P4 first. Then add M3 vs m3.
Sing the reference: Before tapping play, try to sing the song reference in your head. Then check.
Listen in music: When you hear a song, try to identify the interval of the melody's first jump.
Use the piano widget: Tap random keys in the interactive pianos and try naming the interval before counting.
Generate and analyse: Use Starts to generate melodies, then identify the interval of each jump in the piano roll.
Try it
Without playing the notes, choose one pair to practise: P4 vs P5 or M3 vs m3. Sing the first note, predict the interval, then tap the matching reference row above to check your answer. Repeat three times and record which pair still feels uncertain.
Self-check
A P4 spans 5 semitones, a P5 spans 7, a minor 3rd spans 3, and a major 3rd spans 4. If the song reference is hard to recall, use the piano widget to confirm the distance after making your prediction.
Key takeaway
Link each interval to a song you know, then test the reference against isolated notes and real melodies. Start with one contrasting pair, sing your prediction, and keep practising until the distance is easier to recognise than to count.
That wraps up intervals. You now understand the distances between notes - the same distances that define every scale, chord, and melody. Next up: Scales & Keys - how notes are organised into scales, and what being in a key means.
