To attach the ukulele strap:
- Locate the strap button at the bottom of the ukulele body.
- Attach one end of the strap to this button.
- For the other end, loop the string provided with the strap around the headstock, just above the nut, and tie it securely. Alternatively, some ukuleles may have a second strap button near the neck joint.
- Adjust the strap length for comfortable playing.
Ladění ukulele
Your kit includes a clip-on tuner to help you accurately tune your ukulele. The standard tuning for a concert ukulele is G-C-E-A (from top string to bottom string when held).
- Clip the tuner onto the headstock of your ukulele.
- Turn on the tuner. It should display the note being played.
- Pluck the first string (G string). The tuner will show the note it detects.
- Turn the corresponding tuning peg slowly to adjust the pitch. Tighten the string to raise the pitch, loosen to lower it.
- Adjust until the tuner indicates the correct note (G) and the needle is centered, usually turning green.
- Repeat this process for the remaining strings: C, E, and A.
- New strings may stretch and go out of tune quickly. Tune frequently during the first few playing sessions until they stabilize.

Holding the Ukulele
Hold the ukulele against your body, with the back resting against your chest. Support the neck with your left hand (if right-handed) and use your right arm to gently hold the body against your chest. The headstock should be slightly higher than the body.
Basic Strumming
Use your index finger or a pick (not included in this kit, but can be purchased separately) to strum the strings. Strum downwards with the nail of your index finger and upwards with the fleshy part. Practice a simple down-up strumming pattern to get a feel for the rhythm.
Basic Chords
Begin by learning simple chords like C, G, Am, and F. These four chords can be used to play many popular songs. Refer to the included beginner's guide or online resources for chord diagrams and lessons.
Údržba
Čištění
Use the provided cleaning cloth to wipe down your ukulele after each use. This helps remove oils and sweat that can accumulate on the strings and body, preserving the instrument's finish and string life.
Péče o struny
While Aquila strings are durable, they will eventually wear out. Replace strings when they sound dull, become difficult to tune, or show signs of fraying. Your kit includes a spare set of Aquila strings for convenience.
Skladování
Always store your ukulele in the padded gig bag when not in use. This protects it from dust, scratches, and minor impacts. Avoid exposing the ukulele to extreme temperatures or humidity, as this can affect the wood and tuning stability.

Odstraňování problémů
Ukulele Won't Stay in Tune
- Nové struny: New nylon strings stretch significantly during the first few days of use. Tune frequently until they settle.
- Změny prostředí: Fluctuations in temperature and humidity can affect wood and string tension. Allow the ukulele to acclimate to its environment.
- Ladicí kolíky: Ensure tuning pegs are tight enough to hold tension. If they slip, they might need minor adjustment or replacement.
Buzzing Strings
- Umístění prstů: Ensure you are pressing down firmly on the strings just behind the fret.
- Action Too Low: The string height (action) might be too low at the nut or saddle. This may require professional adjustment.
- Uneven Frets: Occasionally, frets can be uneven, causing buzzing. A luthier can address this issue.
