Accidentals on the G Clarinet (Sharps and Flats):
A Practical Guide to Clean Fingering

On the G clarinet, accidentals (sharps and flats) are the point where most students say "I can't finger them cleanly," "the tone cracks," or "it slips during transitions." The good news: this problem is usually not about "talent" — it's about small fingering details, the keys not closing fully, and the wrong order of practice. With the right method, accidentals can be cleaned up quickly.

Goal: Clarity + confidence on accidentals + clean transitions.

The 5 most common problems with accidentals

1) Keys not closing fully (tiny leaks)

On the G clarinet, even a "very small" gap in accidentals ruins the tone. Especially when fingers rise during transitions, keys don't close fully. Solution: Don't lift fingers unnecessarily. Work with a "minimal movement" mindset.

2) Pinky finger confusion

With accidentals, the pinky fingers (side keys) can lock up in fast transitions. Solution: Isolate and practise the pinky fingers separately (see exercise 2 below).

3) Tone cracking / jumping

If the airstream is "pushed" on accidentals, the tone cracks easily or can "jump" to an upper register. Solution: Stabilise the breath, soften entries. Very slow first.

4) Tempo drift during transitions

Focusing on the fingers disrupts the rhythm. Solution: Apply the "error-free tempo" rule (slow-clean) with the metronome.

5) Practising all accidentals the same way

Not all accidentals are equally difficult. Some need "closing" precision, others need "transition" precision. Solution: Choose the 2 accidentals you struggle with most, and spend 7 days only on those. If you need help, visit the video library.

The 3 core rules for clean fingering

12-Minute Accidental Routine (daily)

This routine works for both the lower and upper octave. But starting with just the lower octave in the first week gives faster results.

• 1. 2 min — Single-note stabilisation: Choose your target accidental. 6–8 second long tone. Goal: stable tone without wavering or cracking.
• 2. 4 min — Two-note transition (A ↔ B): Pair the accidental with a neighbouring note. A → B → A → B (very slowly). With each transition, focus on the keys "closing fully."
• 3. 3 min — Pinky isolation: Repeat only the transitions where the pinky comes in and out. Goal: break the "lock-up."
• 4. 3 min — Cleanliness with metronome: Set the metronome to a very slow tempo. 2 clean repetitions → small increase. Error → pull the tempo back.

After 7 days of this routine, you'll notice a clear easing with accidentals.

Exercises: Unlocking and Cleaning

Exercise 1: "Clean entry" (reduces cracking)

• Choose your accidental
• Begin with a very soft entry
• If cracking occurs at the "start" of the tone: don't increase lip pressure — stabilise the breath

Exercise 2: "Lock-breaker" (for the pinky)

• Choose two different transitions that use the accidental
• Do each transition 10 times very slowly
• Reduce finger lifting
• Then try the same transitions with rhythmic variation: long-short, short-long

Exercise 3: "Rule of 3 clean repetitions"

Same passage/bar: play it 3 times in a row cleanly. If even one is messy, slow the tempo and start again. The goal is not "I played it right once" — it's playing it right repeatedly.

Tip: Visual support: You can see koma positions and lip technique in detail in the Koma and Clarinet Application video.

Practical guidance (very useful): If you're struggling with accidentals, follow this order:

If you break this order, practice seems "fast" but results come slowly. You can work with the Education Book to learn accidentals and all other technical topics in the right sequence.
