Hight
Also the pitch affects on how strongly or weakly music is experienced. By playing high up on the piano (eg. An octave higher than normal) you have the opportunity to play more soft than the middle or deep down on the piano. A special way to work with the pitch is to transpose the song - usually towards the end. You transpose usually a half or a whole tone upwards, and without really playing louder you will experience the music grow in intensity.
At present, there is not any clips for illustration of the dynamics by using the pitch.
