The majority of the songs I’ve played in orchestra (I play the violin) have been bought from J.W. Pepper, a music distributer. Their website has professional recordings for many of their pieces, which are incredibly useful when teaching yourself how to play a piece. Knowing how the song goes makes life a lot easier.
However, the audio player (example) they use is nearly impossible to use on an iOS device. The player buffers the entire song, but every time you touch the scrub bar it rebuffers the song and starts from the beginning. It is impossible to jump around in the song, and it is usually far easier to use a native audio player.
Naturally, there is no download link for their MP3’s. They use an HTML-based
player, though, so the Chrome inspector can be used to find the URLs. All of
the sound files I have come across use the same pattern:
http://jwpepper.com/audio/<productID>.mp3. The product ID can be found in the
URL for the player:
The ID is usually a several-digit-long number (i.e. 2433019) This is also
present the product page for a song:
for instance. These patterns are how links are generated on my
orchestra concert pages.
To be clear, the recordings are copyrighted by J.W. Pepper, and they should not be shared. They would probably also frown upon playing the recordings to large groups, too; a bunch of their recordings have tones overlaid every few seconds, and some are missing parts of the original piece.
I personally download the recordings to help me play a piece better, especially when I have to sight-read a piece alone. I download the recordings and put them in iTunes so I can sync them to my phone. (I frequently play recordings to break the silence but not distract myself with lyrics.) On my laptop, I use VLC to play them so I can slow them down without adjusting the pitch like Microsoft products seem to do. (Go Apple!) For fast parts (e.g. 1:40 into Music from Brave), I’ll slow it down to 50% speed, play through the section a bunch of times to get the notes and rhythms right, and ramp the speed up some. It is incredibly useful.
Just remember: don’t steal their recordings. You have been warned.
