Context: <response>: E still dey possible for two sounds wey get indefinite pitch to dey clearly higher or lower pass each other. For example, snare drum dey sound higher pass bass drum even though both of dem get indefinite pitch, because im sound dey contain higher frequencies. In other words, e dey possible and e dey easy sometimes to sabi roughly the relative pitches of two sounds wey get indefinite pitch, but sounds wey get indefinite pitch no dey neatly correspond to any specific pitch. A special type of pitch dey happen for free nature when sound reach the ear of person directly from the source, and also after e don reflect off sound-reflecting surface. This thing wey dey happen na repetition pitch, because the addition of a true repetition of the original sound to itself na the basic prerequisite.
