Module 16: Extended Techniques
Double Tonguing (Tu-Ku)
When the tempo exceeds 140bpm, the single tongue (Tu) cannot keep up. We engage the back of the tongue (Ku).
The Seesaw: While 'Tu' strikes just behind the front teeth, 'Ku' (or a softer 'Gu') is formed by the back of the tongue arching up against the palate. Keep that contact as far forward and as light as you can, so the 'Ku' stays crisp and matches the 'Tu' instead of sounding swallowed or sluggish. Tu-Ku-Tu-Ku.
Pro Tip: The 'Ku' is naturally weaker. Practice 'Ku-Ku-Ku' alone to strengthen it until it sounds identical to 'Tu'.
Triple Tonguing (Tu-Tu-Ku)
This is for triplets (groups of 3). Think of the word 'Difficult'. NEW-york-er, NEW-york-er.
Patterns:
- Standard (Arban): Tu-Tu-Ku. Best for fanfares and marches like 'Bugler's Holiday'.
- Alternating (Clarke): Tu-Ku-Tu, Ku-Tu-Ku. Best for smooth, flowing runs.
Flutter Tongue
Roll your tongue like a Spanish 'Rrrrr'. You must keep the air moving FAST to keep the tongue flapping.
Can't Roll? Some people genetically cannot roll their Rs. Alternative: 'Growl'. Gargle the back of your throat (uvula) while playing. It sounds effectively the same.
The Growl (Jazz)
This creates a dirty, aggressive sound. To do it, simply sing/hum a random note in your throat while buzzing. The two frequencies (lips vs vocal cords) clash, creating 'heterodyne' interference beats that sound like rasp.
