Keep getting matrix dimensions must agree for code

For my engineering 101 class, we have to code a song into MATLAB. For some reason, I keep getting the same error code. Any help is appreciated.

jakenote is the code my professor gave us to work with and music2 is what I've done so far.

Wow, I see why you want help, now that I know where the error is. What is this line supposed to do? Is there any way of breaking it into smaller pieces?

>> size(A4e+F4SHARPe)

ans =

             1       11025

>> size(F4SHARPq+D4q)

ans =

             1       22050

>> size(Re)

ans =

             1       11025

>>

As you can see the sizes mismatch in order to remove the error the sizes should be the same
