Mozart c.1984!

MOZART c.1984!


by Chi-Yeung Choy


from ZX Computing Jun/Jul.1984





Chi-Yeung Choy of Ruislip flexes his fingers and


performs this musical masterpiece.








The Spectrum's oft maligned beep has been considered too


feeble for any reasonable musical application in the past,


but now we present a program which will make you think


again!





Instead of the usual selection of sound effects or brief


burst of barely recognisable tunes, Chi-Yeung has


successfully programmed a computer version of the first


movement of Mozart's piano sonata in C Major K545. What is


even more amazing is that it is written all in BASIC and


fits into the 16K machine!





A great deal of thought and attention to technical detail


has gone into this program. For instance, the subroutines


have been put at the start of the program to get every ounce


of speed from the computer.





Chi-Yeung tells us that his greatest problem was fitting it


into the 16K due to the amount of DATA required and that he


almost gave up. Type it in and then give your fingers a rest


and your ears a treat. Play on maestro!
