Rearranging existing 2-hand repertoire into single-hand: 

Both our Armenian and Azerbaijani composers wrote for normal healthy pianists with normal ten fingers. I had a challenge transcribing melody and bass and inner chords into five fingers. Luckily I had a precedent of Godowsky doing just that. Studying Godowsky's 'studies' on Chopin's 'studies', helped me a lot in transcribing Andriasian and Quliyev.

DJ Ha is a pianist who studied with Alexandra Vinokurov and Aleksei Nasedkin. In his youth he was injured with a stroke, but thanks to discovering Godowsky, he resumed playing, this time with left hand alone. Instead of focusing on what he missed (use of right hand, accompanying, chamber music), he now makes up in teaching and composing.

Diana Weston (M.Mus) is a harpsichordist, square pianist and founder of the early music ensemble Thoroughbass.

She has commissioned new works, featured unusual and eclectic repertoire and produced many compact discs. Some of the more notable of her projects include Cock Crow (with poetry), Debussy's The Toybox (ballet music and story-telling), Glass' opera Akhnaten (with scent), and the production of F. Caccini's early opera Alcina (as Ondine Productions). Of late, Diana's main areas of interest have included research and performance on early pianos, and her continuing association with international keyboardist Dr Michael Tsalka. Diana is one half of Mary & Me, a piano duo of like-minded friends.
