Counting Triplets.
A triplet, as the “tri” in the name implies, means three. It’s the subdivision of the beat into three even parts. Notice that I had used the word three for the number 3 in my writing. So, if I’m counting any beat which can be sub divided by three, it’s 1 2 3. No need to use words such as trip-o-let or one triplet, two triplet, etc to count.

Strums are Inseparably Linked to Rhythm. Any strum can be broken down to its Modular Phonetic rhythmic syllables. Modular Phonetic Rhythm, by Chuck Anderson is a system for learning rhythm. It teaches rhythm phonetically - just as language does. Remember 'Strums ARE rhythm'
Counting Triplets.

Learn a variety of strums and rhythmic patterns in wide range of musical styles. One of the first skills a ukulele player learns is the art and craft of strumming, playing rhythm. This refers to an accompaniment technique suitable for the singer, singer - songwriter or someone who plays a support role for another instrument.

Modular Phonetic Rhythm represents a significant advance in the teaching and application of rhythm. Eliminating many inefficient aspects of rhythm education, Modular Phonetic Rhythm streamlines the traditional educational approach, resulting in a reflexive reaction to rhythm.
