I wondered if anyone else has come across Recitalworks yet?
It's a collection of downloadable piano pieces by Philip Johnston (the chap behind Practicespot and author of several books). He's to music education as Laurel is to Hardy! It seems that he is also a good composer and performer.
Like other sites you can download the score and listen to it being played (as MP3 and stream). However, what I like about this site is that once you have paid for the score to be unlocked, you can print as many copies off as you like, as long as it's from the computer you downloaded it from.
There are 11 pieces on the site at the moment in a mixture of styles, going upwards in complexity from about Grade 5. I'm sure that some of my students will like to play what's on offer here - I know that I will be downloading some. With the promise that there will be more pieces soon, it's a site I shall visit again.
