Of this series of twenty-four études planned by Liszt only twelve were actually written, but the contemporary printed editions of the completed pieces (in the hope of a continuation) appeared with the series title 24 grandes études. By publishing these 12 concert studies it makes the earlier and technically more difficult version of the Transcendental Studies available for the first time since 1911 for study by performers and those engaged in music research.
Contrary to the 1911 edition among the volumes of the first complete Liszt edition, NLE will publish also the text variants of some studies, an album leaf in F sharp major in facsimile and in transcription considered asthe 13th study planned by Liszt for the series, and the earlier versions of the so-called Mazeppa and Ab irato studies.
In the volume will be published the puzzling album leaf, the so-called ''Prélude omnitonique'' and some similar album leaves, too.
