The 1-ee-and-uh Drill combines every 4-beat combination of two tones, for example "don" (drum center) and "da" (drum edge). The 16 total combinations represent a significant portion of the sticking combinations used in taiko. LATI postulates that a deep understanding of these combinations, and the ability to apply the drill to a variety of tones, empowers players to systematically identify dexterity challenges.
Earning the 1-ee-and-uh LATIdama signifies that you have attained a high level of proficiency with the drill's form and understand how to further apply the drill concepts to future practice.
For detailed information on the LATIdama system, see LATIdama.
Good luck and have fun!
