A typewriter keyboard instrument wherein the keyboard is arranged as a standard typewriter with only letters, numbers, and symbols of the standard keyboard wherein the key with the letter N is assigned to play the note middle C, and wherein each succeeding key to the right plays a note which is a half-step higher than the note played by the preceeding key, and two expanded keyboards; the first expanded keyboard having five additional keys on each end of each row, wherein each additional key plays a note one half-step lower or higher than the adjacent key; and the second expanded keyboard having five additional keys on the right hand end of each row of keys and seven additional keys on the left end of each additional row wherein each additional key plays a note which is one half-step higher or lower than the adjacent keys, and wherein the music for the standard and the expanded keyboards is written with a key designation in the clef and wherein the dark notes have a light letter corresponding to the key to be pressed and the light notes have a dark or black letter in the center thereof to designate the key to be pressed, and wherein an ordinary typist with only a basic knowledge of music can sit down to the instrument, readily read the music, automatically correlate the music to the keyboard, play the instrument and, at will, transpose to any new key to play the music in, simply by moving the placement of his/her home row fingers location to the left or right of the original home row on the expanded keyboards.
