  1. Look for the brand’s logo near the center of the keyboard.
  2. Below the logo, find the set of two black keys.
  3. The white key immediately to the left is Middle C.

Middle C serves as a reference point for locating other notes and ultimately forming chords like the C7. Once you find Middle C, you can easily navigate the keyboard to play any song or chord.
