Fair dealing permits copying of an entire single musical score from a copyright-protected work containing other musical scores.
The key point is that it must be part of a collection of musical scores. Copying of an entire musical score that is not in a work containing other musical scores is NOT permitted without obtaining permission.
Fair Dealing allows up to 10% of a musical work to be copied. So if a book contains a number of songs or musical scores then you can copy the greater of one musical work or 10% of the book. If the musical score is not contained in a book with other musical scores then fair dealing limits the copying to 10% of a score (which is not generally all that useful).
If you need to obtain permission, generally the music publisher is a good place to start. At times the right to copy music is given when the music is purchased. In these cases the music books or sheets will have a notice stating that copying is permitted and no further permission needs to be sought.
