- Master the thumb half-hole technique for high C5
- Understand octave relationships and the second register
- Play smooth transitions between first and second octave notes
- Learn "Twinkle Twinkle Little Star" with high C
Introduction
Congratulations on reaching one of the most important lessons in recorder playing! Today you'll learn high C, which opens up an entirely new octave of notes. This requires mastering the thumb half-hole techniqueāarguably the most crucial skill on recorder.
Understanding Octaves
An octave is the distance between one note and the same note higher or lower. For example:
- Low C (C4) - We haven't learned this yet
- Middle C (C5) - This lesson's goal! ā
- High C (C6) - Advanced technique
The recorder has two main registers (octaves). Moving between them requires a special technique with your left thumb.
The Thumb Half-Hole Technique
Until now, your left thumb has completely covered the back hole. To play second-octave notes like high C, you need to partially uncover the thumb holeāthis is called a "half-hole" or "pinch."
How to Form the Half-Hole
- Start with your thumb completely covering the back hole
- Slide your thumb DOWN slightly (toward the floor) while keeping the pad in contact
- Expose a tiny crescent of the holeājust 1-2mm!
- Your thumbnail should still point toward the ceiling
- Think "pinch" not "lift"āyou're rolling, not removing your thumb
Common mistake: Lifting the thumb completely off instead of sliding it. This causes squeaks!
Note: High C5
Fingering for High C: Thumb half-hole + first two fingers (the same finger position as low A, but with a pinched thumb)
Play long, steady high C notes. This will probably squeak at firstāthat's normal!
Troubleshooting:
- Too squeaky? Your thumb hole might be too open, or you're blowing too hard
- Sounds like low A instead? Your thumb hole isn't open enough
- Airy, weak sound? Increase breath support slightly, or adjust thumb
Octave Leaps
Moving smoothly between low and high notes is essential. Practice these transitions slowly.
Start with A4 (thumb fully covered), then move to C5 (thumb half-hole). Focus on the thumb motion.
Goal: No squawks when changing notes! Smooth, confident transitions.
A bigger leap. Keep your fingers relaxed and move smoothly.
Your First Second-Octave Song: Twinkle Twinkle Little Star
This beloved melody uses high C prominently. You already know most of the notes!
First line - "Twinkle twinkle little star"
Second line - "How I wonder what you are"
Tip: Start very slowly. Speed means nothing if the notes aren't clear!

Thumb Half-Hole Mastery Tips
- Daily practice - Spend 5 minutes every day on high C alone
- Mirror check - Watch your thumb in a mirror to see if you're sliding correctly
- Slow motion - Practice thumb movements without blowing first
- Relax - Tension makes the thumb stiff. Stay loose!
- Patience - Most students need 1-2 weeks to really nail this. You're not slow if it takes time!
Breath Control for High Notes
High notes require slightly more air speed (but not more volume) than low notes. Think of it like blowing a candle flameāgentle but focused.
- ā Use more air speed, not more air volume
- ā Keep air stream steady and focused
- ā Don't blow harderāthat causes squeaking
- ā Don't puff your cheeksāthis reduces control
