The beautiful Invention in a minor is almost exclusively constructed from broken chords, creating a surprisingly rich musical texture considering the piece has only two voices. It is structured similarly to a fugue in miniature, alternating entries of its main subject with longer episodes used to modulate to new keys. Carefully chosen and practiced fingerings will be key to letting the hands navigate the broken chords that wind up and down the keyboard with independence and ease.
Musically, there are several approaches to character and articulation that could potentially suit the material, offering the pianist an excellent opportunity to sharpen their interpretative skills. For example, the minor key and musical motifs could imply an agitated, fiery character or a softer, graceful approach. The eighth notes can be played with a sharp staccato, a subtle portato, or even legato – or the articulation might even vary across the piece, with certain notes bound together, and others separated!

"I was in Poland the past summer to give 2 concerts. At the last minute they requested some Chopin, which I had not brought with me. So, I google-searched for classical downloads and found your site. I was able to print out excellent editions of the pieces I needed within minutes. To find the scores locally would have been inpossible as it was a smaller town, the nearest music store 45 minutes away."
"Piano Street has been a wonderful tool to me as both a pianist and a piano teacher. I can browse the collection for pieces I want to play and/or have my students play. The difficulty rating system that Piano Street uses enables me to search by difficulty level for pieces at my students' various playing levels. It is helpful that many of the scores include an audio clip of the piece being played. I have recommended to my advanced students that they also join Piano Street since getting sheet music from there is a much less expensive alternative to ordering and paying for the music.
