MIDI-files
Musical Instrument Digital Interface
These files download a series of instructions to your PC to play the notes of the music with the same instrumental sounds as the original.
They enable your PC to play the music using a Media-player program - which most PC's have as part of the soundcard software 'bundle' or as part of the Windows package. The quality of the playback depends in a large part on the type and quality of your soundcard, and how it has been integrated into your PC.
If you are unable to play the MIDI-files you may need to download a player from www.microsoft.com/windows/mediaplayer or by clicking on this logo. There is no charge for the player.

Sibelius-files
These files also download a series of instructions to your PC to play the notes of the music with the same instrumental sounds as the original.
Sibelius files also show you the manuscript copy of the music which is being played.
Since your PC will be playing the music, the quality of the playback will depend on the type and ability of your soundcard.

If you are unable to play the Sibelius-files and the music page remains blank, you should follow the instructions at the foot of the page and click on the blank space. This will take you to the Sibelius Software site, from where you can download the Scorch file player which will 'run' the file.
The 'player' remains in your PC allowing you to play any Sibelius-files which you come across in the future.
Clicking on www.Sibelius.com will access the company's Home-page. There is no charge for the player.

RealAudio-files
This is a file in which a recording of a piece of music is sent as a continuous stream of data to your PC and your soundcard recreates the sound of the original recording.
It takes a little time to start as the first 3 / 5 seconds arrive and are stored in your PC in a 'buffer' memory. The file builds up at the same rate as the music is played until the piece is completed.
Sound quality is comparable to AM radio.
If you are unable to play the RealAudio-files you may need to download a player from RealAudio
or one of the major share-ware net-sites. There is no charge for the player.

MP3-files
MusicPlayer, third edition - files
This is a file transfer in which a recording of a piece of music is sent as a complete file, which is then played by your PC.
Depending on your MP3 Player you may need to download the complete file before it runs.
Sound quality is comparable to FM radio.
Both the Windows MediaPlayer and the RealAudio Player are capable of playing MP3 files.
