To hear this file, you should install a plug-in permetting you to see and hear this kind of Myriad Music programs;

it's working very well with Chrome and it's better on Internet Explorer even if the installation is a little bit complicated.

If the installation doesn't start automatically, you can get freely this plug-in at their download site: http://www.myriad-online.com/cgi-bin/download.pl?prod=MM&lang=FR

Use the tool in the top of the partition you will see for having the possibility to transpose... and adjust the sound for each voice.

I made another version with orchestra, see : .../Graduale-orch.htm
