The wavelet representation of a signal has many similarities with conventional musical notation. The frequency of these variations gives us the pitch of a sound.
Higher frequencies result in higher pitched notes and vice-versa.
Complex sounds such as a piece of music are made up of many different notes containing different frequencies which change over time as the melody and harmony progress. The language of reading and writing music is the score. Example of musical notation. The five horizontal lines are known as the stave. Higher notes are written higher on the stave.
