Hi Mark & Michelle
£20 seems expensive but I suppose it depends on the complexity of the score etc the last Original sheet music I purchased was “Here With Me” DIDO £3.50 there is no text on the pages referring to copyright however on “The Air That I Breathe” sheet music it states” Reproducing this music in any form is illegal and forbidden by copyright, Designs and Patents Act 1988” sometimes people may need to photocopy their own music because its easier to see the whole score rather than turning over the many pages but we should not really copy it but copyrighting is a complex issue and this topic as been covered many times on the forum As we all know companies have very skilled people out there in a bid to try and stop the copying of their music, software etc however there are equally clever people out there trying to get around there systems so it’s a constant battle.
Regards
Pete
