Some might be familiar with this wonder app.
There are apps on the web where one can scan with their scanner, a music score and have it played back through the PC.
Playscore2 takes this a step further.
One only has to photograph a piano score with their ipad, smart phone
(if camera is a good one) and it is ready for playback.
It's FREE.
But for a small monthly/yearly subscription, an orchestral version is available.
A range of instruments being assigned as required.
This brings all of copyright free classical, piano/orchestral music to your films.
There are old books of music scores for sale from various sources on the net.
I've just bough a book of music scores of Brahms piano works for a few quid,
for example.
Playscore2 is not available for Windows, only Apple and Android.
Happy photographing

AND BY THE WAY........It's British !
