Setup
1. Assembly
- Carefully remove all three sections of the recorder from the carrying bag: the head joint (mouthpiece), the middle joint, and the foot joint.
- Apply a small amount of the included joint grease to the cork or plastic joints of the middle and foot sections. This ensures smooth assembly and prevents damage.
- Gently twist the middle joint onto the head joint. Align the finger holes for comfortable playing.
- Attach the foot joint to the middle joint, twisting gently. Ensure the holes on the foot joint are aligned with the lower finger holes of the middle joint for proper fingering.
2. Holding the Recorder
Hold the recorder with your left hand at the top (head joint) and your right hand at the bottom (foot joint). Your left thumb covers the back hole, and your left index, middle, and ring fingers cover the top three holes. Your right thumb supports the recorder from underneath, and your right index, middle, ring, and pinky fingers cover the remaining holes. Ensure a relaxed grip to allow for agile finger movement.
Operating (Playing the Recorder)
1. Embouchure and Breathing
Place the mouthpiece gently between your lips, forming a soft seal. Avoid biting or applying excessive pressure. Breathe from your diaphragm and blow a steady, gentle stream of air into the recorder. The goal is to produce a clear, consistent tone without excessive breathiness or squeaking.
2. Fingering
The Yamaha YRA-28B uses Baroque fingering. Refer to the included fingering chart for specific finger positions for each note. Ensure all holes are completely covered by your fingertips to produce clear notes. Partially covered holes will result in airy or incorrect tones.

Maintenance
1. Cleaning After Each Use
- Disassemble the recorder into its three sections.
- Thread a soft, lint-free cloth through the cleaning rod.
- Gently push the cloth through each section of the recorder to remove moisture and condensation.
- Wipe the exterior of the recorder with a clean, dry cloth.
2. Joint Care
Periodically check the joints for dryness. If they appear dry or assembly becomes difficult, reapply a small amount of joint grease. This prevents wear and tear and ensures a proper seal between sections.
3. Storage
When not in use, store the disassembled recorder in its cotton bag. This protects it from dust, dirt, and temperature fluctuations. Avoid storing the recorder in direct sunlight or extreme temperatures.
Troubleshooting
- Squeaky Sound: This often indicates that a finger hole is not completely covered, or you are blowing too hard. Ensure all holes are sealed and use a softer breath.
- Difficulty Producing Notes: Check your fingering against the chart. Ensure the joints are properly assembled and sealed. Condensation in the windway can also cause this; clean the recorder thoroughly.
- Airy or Weak Tone: This can be due to insufficient breath support or improper embouchure. Practice blowing a steady, focused stream of air.
