The mark is a sound. The mark consists of two quarter notes followed by 4 eighth notes. The first quarter note is a C followed by a second quarter note of a D. The eighth notes are then an E, a G, a B, and a C in consecutive order. This defining melody is the sound of a human whistling. The last 8th note played is accentuated with a female vocalist singing a scooped G over the whistled last C note. Further instrumentation includes an acoustic guitar playing a C chord over the last note layered with a bass instrument. The logo is accentuated with percussion bounces and a percussion run to match the animation. The percussion sound is similar to striking a coconut shell with wood mallets.
