If you are looking for Grade 1 classical repertoire, you may want to check out the recent edition entitled "Classics Exploration" by Charles Wu. It is a self-published edition, and is available in PDF as a FREE download. Mr. Wu has obviously put a lot of care and attention to detail in creating this e-book, which contains pieces from the standard teaching repertoire, including:

Georg Frederic Handel – March in G HWV 419/3
Henry Purcell – Air in D Minor ZT 676
Domenico Scarlatti – Sonata in C Major K. 73B
Franz Joseph Haydn – German Dance Hob. IX/22 No. 3
Wolfgang Amadeus Mozart – Minuet in F K.2
Daniel Gottlob Türk – 'Horn With Echo' from 49 Pieces for Beginners at the Piano
Robert Schumann – ‘Soldier’s March’ from Album for The Young Op. 68
Theodore Oesten – ‘Echo’ from Mayflowers Op. 61
Robert Fuchs – ‘Sad at Heart’ from Album for the Young Op. 47
Cornelius Gurlitt – 'The Rope Dancer' from Little Studies Op. 130
Stephen Heller – ‘Scabieuse’ from Album for the Young Op. 138
Friedrich Burgmüller – ‘L’Arabesque’ from 25 Progressive Studies Op. 100

They are typeset very cleanly, and are accompanied by some brief but helpful teaching notes by Mr. Wu. The pieces contained in this volume are all in the public domain, so download away with a clear conscience!

I'm not sure how long this is going to be available as a free download, but it is currently available by clicking here.

UPDATE - NOVEMBER 6, 2011
This e-book is now also available from the Amazon store as a download for Kindle. Amazon does not permit free downloads, so the price is $ .99. You can still download as a PDF from the free link.
