A method of playing a musical keyboard comprises four main steps. The first step involves providing a guide comprising multiple columns aligned with keys on the musical keyboard. The columns are further divided into rows defining multiple blocks containing color codes and numbers. The numbers are arranged in arithmetic progression in each color code extending across a single row. The second step involves playing a first key on the musical keyboard based on a selected color code represented in each predetermined row. The third step involves playing the subsequent keys on the musical keyboard as per the arithmetic progression of numbers in the subsequent rows. The fourth step involves shifting to a subsequent row of the sheet, to start playing a selected key and the subsequent keys on the musical keyboard based on the next color code and corresponding numbers represented in the subsequent rows.

An extruder screw for use in a barrel of an extruder for forwarding thermoplastic polymer from a first end to a second end of the extruder. The extruder comprises a transition section and at least one flight extending substantially along the length of the screw. A dam is positioned at the point where the rapid melting of the solids starts to slow down and the rate of solid bed width decrease approaches zero. The dam provides the screw with a high output of extrudate and close control of the residence time of polymer particles as they are transported through the screw, resulting in an extrudate which is uniformly melted and which is substantially free of degradation products and/or entrapped air.
