Identify Notes that are 3 Tones and 3 Semi-tones Apart
Listen to or play pairs of notes on a keyboard and identify whether they are three whole tones (six semitones) or three semitones apart.
About this activity
Listen to or play pairs of notes on a keyboard and identify whether they are three whole tones (six semitones) or three semitones apart.
What you need
Step by step
- 1
Step 1
Place the keyboard and put paper pencil and colouring materials next to it so they are easy to reach.
- 2
Step 2
Sit comfortably and press any key once to choose and hear your starting note.
- 3
Step 3
Press the very next key to the right and listen to hear a single semitone above the starting note.
- 4
Step 4
From the starting note move one key at a time to the right and count each move aloud until you reach 3 then stop.
- 5
Step 5
Press the key where you stopped to hear the note that is 3 semitones above the starting note.
- 6
Step 6
From the starting note move one key at a time to the right and count each move aloud until you reach 6 then stop.
- 7
Step 7
Press the key where you stopped to hear the note that is 6 semitones (three whole tones) above the starting note.
- 8
Step 8
On your paper write Pair 1 through Pair 10 as empty slots so you have ten practice rounds.
- 9
Step 9
For each pair decide secretly whether you will make it a 3-semitone pair or a 6-semitone (three whole tones) pair and write that choice privately next to the pair number.
- 10
Step 10
Play each pair on the keyboard while keeping your paper hidden and listen carefully to the two notes.
- 11
Step 11
After listening to a pair write your guess next to that pair number as "3 semitones" or "3 whole tones."
- 12
Step 12
Check every guess by counting one key at a time from the lower note up to the higher note and see if you counted 3 or 6 semitones; mark correct answers.
- 13
Step 13
Tally how many you got right and write your score on the paper in a bright colour.
- 14
Step 14
Share your finished creation and score on DIY.org.
Fun facts
How do I teach my child to identify whether two notes are three whole tones (six semitones) or three semitones apart?
Start by showing the keyboard layout and explain semitone and whole tone spacing. Play a reference note, then play the second note and ask the child to listen. Count steps on the keyboard together (three semitones = three keys including black keys, three whole tones = six semitones). Use slow, repeated examples, sing the intervals, and give immediate feedback. Gradually remove visual counting so the child learns to recognize the sound by ear.
What materials do I need to do this notes-interval activity at home?
You’ll need a keyboard or piano (acoustic or electronic) and a simple keyboard diagram or stickers to mark keys. A smartphone app or tuner can play reference notes and record sessions. Headphones help in noisy homes. Optional materials: interval flashcards, a metronome for consistent timing, and a notebook to track progress. No special music reading ability is required to start.
What ages is this ear training activity suitable for?
This activity suits children roughly aged 6 and up. Younger children (4–5) may enjoy simple listening games but might struggle with counting semitones. Ages 6–9 can learn counting and basic recognition with visual aids, while 10–14 can refine ear training and work without visual cues. Adjust pace to attention span and prior musical exposure, and offer supervision and encouragement for best results.
What are the benefits of practicing intervals like three tones and three semitones?
Practicing these intervals improves relative pitch, listening skills, and musical memory. It helps with instrument playing, sight-singing, and tuning, while sharpening concentration and pattern recognition. Regular practice builds confidence and ear independence, making it easier to learn melodies and harmonies. For children, it also supports auditory discrimination skills useful in language and math development.
Watch & Learn

What can we use if we don't have a physical keyboard for the step 'press any key once to choose and hear your starting note'?
Use a free piano or keyboard app on a tablet or phone and keep your paper, pencil and colouring materials beside it so you can tap any onscreen key just like the instructions say.
I'm losing track when I 'move one key at a time to the right and count each move aloud'—how can I avoid mistakes?
Place a small sticker on your chosen starting key, slide your finger to touch each key as you count aloud, and replay the stopped key to check whether you reached 3 or 6 semitones per the counting steps.
How can I adapt the activity for younger or older children when the instructions ask to make Pair 1 through Pair 10?
For younger kids, cut the practice to 4–6 pairs and use coloured stickers on starting and target keys to help them count, while older kids can keep all ten pairs and add challenges like timing rounds or using notes across different octaves.
How can we extend or personalize the activity after we 'tally how many you got right and write your score on the paper in a bright colour'?
Turn it into a points game (for example 2 points for a correct '3 whole tones'), decorate your paper with colouring materials, record short audio of each pair as extra practice, and photograph the finished sheet and score to share on DIY.org.
