Introduction
This manual provides essential information for the proper setup, operation, maintenance, and care of your Hisonic Signature Music Open Hole Silver Low C Flute, Model 2820S. Please read these instructions carefully to ensure optimal performance and longevity of your instrument. This flute is designed for intermediate to advanced players.
Setup
1. Unpacking the Flute
Carefully open the protective carrying case. The flute components are typically secured within the case to prevent movement during transport. Remove any packaging materials such as plastic wraps or silica gel packets.

2. Assembling the Flute
- Attach the Footjoint: Gently hold the body of the flute (the longest section with most keys) and align the footjoint (the shortest section) with the rod extending from the body. Twist gently with minimal pressure until it slides into place. Avoid gripping the keys.
- Attach the Headjoint: Hold the body of the flute and carefully slide the headjoint (the tapered section with the embouchure hole) onto the other end. Twist gently until it is securely in place. Ensure the embouchure hole is aligned with the first key on the body.

3. Using Hole Plugs (Optional)
This open-hole flute comes with hole plugs. If you are new to open-hole flutes or prefer to play it as a closed-hole instrument, you can insert these plugs into the open keys. This allows for easier fingering while you adapt to the instrument. The plugs can be removed individually as your skill progresses.
Operating the Flute
1. Holding Position
Hold the flute horizontally. Your left hand supports the flute closer to the headjoint, with your fingers positioned over the keys. Your right hand supports the flute closer to the footjoint, with your fingers also positioned over the keys. Maintain a relaxed posture to allow for free movement and breath support.
2. Embouchure
Forming a proper embouchure is crucial for producing sound. Place the lip plate against your chin, just below your lower lip. Direct a focused stream of air across the embouchure hole, aiming for the opposite edge. Experiment with lip tension and air angle to produce a clear tone.
3. Fingering
Refer to standard flute fingering charts for specific notes. For open-hole flutes, ensure your fingertips completely cover the open holes to prevent air leaks, unless a specific technique requires partial coverage. If using plugs, treat the instrument as a closed-hole flute for fingering purposes.
Maintenance and Care
Regular maintenance is essential to keep your flute in optimal playing condition.
1. Cleaning After Each Use
- Swabbing the Interior: Use a cleaning rod with a soft, absorbent cloth (like the one provided) to swab the inside of each flute section. This removes moisture and prevents corrosion.
- Wiping the Exterior: Gently wipe the exterior of the flute with a soft, lint-free polishing cloth to remove fingerprints and oils. Avoid harsh chemicals or abrasive materials.
- Pad Care: If pads become sticky, gently place a piece of cigarette paper or a specialized pad cleaning paper under the sticky pad, press the key, and pull the paper out. Repeat until the stickiness is gone.
2. Silver Plating Care
The flute features silver plating. To maintain its luster, store the flute in its case when not in use. Avoid prolonged exposure to air and humidity, which can cause tarnishing. If tarnishing occurs, use a silver polishing cloth specifically designed for musical instruments, following the product instructions carefully.
3. Storage
Always store your flute in its protective carrying case when not in use. Ensure all sections are properly disassembled and placed in their designated compartments to prevent damage to keys and pads.

Troubleshooting
Here are some common issues and basic solutions:
- No Sound or Weak Sound:
- Check embouchure: Ensure a focused air stream and proper lip tension.
- Check key coverage: Make sure all open holes are fully covered by fingertips or plugs.
- Check for leaks: Lightly press each key to ensure pads are sealing properly. Sticky or worn pads can cause leaks.
- Sticky Keys:
- Clean pads as described in the Maintenance section.
- Ensure the flute is dry before storing.
- Keys Not Moving Freely:
- Check for bent keys or rods. If visible, do not attempt to bend them back yourself.
- Ensure no foreign objects are obstructing key movement.
For persistent issues or mechanical damage, it is recommended to consult a qualified instrument repair technician.
