- 5
Step 5
Turn the tuning peg for that string slowly to raise or lower the pitch until the tuner shows the correct note and the indicator is centered or green.
- 6
Step 6
Pluck the same string again to check the tuner and make tiny adjustments if needed.
- 7
Step 7
Move to the next string below and repeat Steps 3 to 6 for each remaining string until all strings are tuned.
- 8
Step 8
Turn on the tuner app’s reference tone feature so you can hear a steady pitch.
- 9
Step 9
Listen carefully to the reference tone for one string and focus on how it sounds.
- 10
Step 10
Without looking at the tuner, pluck the matching string and try to match its pitch to the reference tone by ear.
- 11
Step 11
Turn the tuning peg slowly while listening until the string matches the reference tone by ear.
- 12
Step 12
Strum a simple chord or play each open string in order to check the overall sound.
- 13
Step 13
If any string still sounds off, re-tune that string using the tuner and your ear.

Take a photo or short video of your tuned instrument and share your finished creation on DIY.org.
Fun facts
How do I teach my child to tune a ukulele or guitar?
Start in a quiet room with the instrument and a tuner app or clip-on tuner. Pluck one open string, watch the tuner to see whether the pitch is flat or sharp, then slowly turn the tuning peg to raise or lower pitch until the tuner indicates “in tune.” Repeat for each string. For ear training, play a reference note then have the child match it by ear. Recheck all strings after tuning because adjustments can shift tension.
What materials do I need to tune a simple string instrument?
You need the ukulele or guitar, a tuner (clip-on, pedal, or smartphone app) and something to pluck strings (fingers or pick). Optional items: a spare set of strings, string winder, soft cloth to wipe the instrument, and a quiet space or headphones for the app. An adult supervisor and a small stool or music stand help smaller children reach the instrument comfortably.
What ages is tuning a ukulele or guitar suitable for?
Tuning can start with adult help as early as 5–6 years old, focusing on listening and basic turning of pegs. Around 8–10, many children can tune with a tuner app and minimal supervision. Younger kids benefit from hands-on guidance; older children can practice ear tuning and learn string names. Fine motor skills and patience are the main requirements rather than a strict age cutoff.
What are the benefits of teaching children to tune their instrument?
Learning to tune builds ear-training, concentration, and fine motor skills. It teaches responsibility for instrument care and helps children hear pitch differences—valuable for singing and playing. Repeated tuning practice also improves patience and problem solving. Simple safety benefits include learning not to overtighten strings to avoid breakage; supervising adults can show safe peg handling and how to change strings if needed.
Watch & Learn

What can we use instead of a tuner app if we don't have one?
If you don't have a tuner app, use a free online chromatic tuner in your phone or computer browser or a pitch pipe/tuning fork to provide the reference tone mentioned in Step 9.
Why won't the tuner center when I turn a peg, and how do I fix it?
If the tuner won't center when you turn a tuning peg, first confirm the app is set to chromatic mode or your instrument (Step 2), then slightly loosen the string, wind it properly around the peg, and re-tune while plucking as in Steps 3–6.
How can I adapt this tuning activity for younger or older children?
For younger kids, have an adult hold the instrument and guide turning the tuning peg while the child listens to the reference tone in Step 9 and practices matching one or two strings, while older kids can tune all strings by ear using Steps 9–12 and check chords in Step 12.
How can we make the tuning activity more fun or personalized before sharing it on DIY.org?
Personalize the activity by adding colored stickers to each string and peg, record a before-and-after short video as required in Step 14, and try an alternate tuning to show a creative variation when you share on DIY.org.
