Play Command Error

I'm using v7. Please try this code:

ClearAll["Global`*"]

notes=Table[N[(440/64)*2^((n+3)/12)],{n,60,72,1}];

Play[Sin[# 2 Pi t]&/@notes ,{t,0,.5}]

Sound::ssnm: A good PlayRange could not be found since most of the
samples are not evaluating to machine-size real numbers. >>

I cannot understand why this error message is produced. Can anyone
help? The values for the "notes" are certainly machine-sized! What's
causing the Sin[# # Pi t] expression to NOT produce valid resuls?
