This short program by M. K. Smith of Mottingham, London, enables your BBC B to play any tune to do is to key-in the note, for example F#; if you need B flat, use A#, which is the same.

You can adjust the volume of each note by typing in any number from 0 to 15; typing 0 will give you a rest in the tune. Keying one of the numbers at the top of the screen will determine the duration of each note. When asked for the octave, you type 'H' for an octave higher than B, otherwise press RETURN.

When you have entered all your notes, type 'S', press RETURN four times, and then sit back and enjoy the music.
