Help on a Matlab question

Hello everyone. So I'm still getting to learn more about Matlab but I could use your help with this question.

A musical semitone is a frequency interval corresponding to the twelfth root of 2 (i.e. 2^(1/12)). We can number semitones with respect to the 'A' above middle C which has the frequency 440Hz, i.e. semitone 0 = 440Hz, semitone 1 = 466.2Hz, etc. Write a program which plays the Westminster chimes, with

            tones=[ 0 –4 –2 –9 –9 –2 0 –4 ];
