The main idea of this logo is taken from the well-known and main scale C major, music notes, and the symbol of silence in music theory. It starts from the left with “do whole note” at the lowest staff, indicated by a vertical line from above, and is read in order of the next notes until it reaches “do whole note” again at the highest staff, indicated by a vertical line from below on the right side of the logo. Additionally, the symbol of silence is in the form of a line and a black rectangle above it, forming the center of the logo. So, the overall appearance of the logo is that from “do whole note” to the next “do whole note,” there is silence (which is somewhat similar to the word “heech” meaning “becoming one with existence” in Persian language), and it also shows the first letter “h” of the word “heech” in the end
