The likelihood is that Bruno Walter designed his transcriptions of Mahler’s First and Second Symphonies for public performance. Dynamics, phrasings and accents have been dropped in with forensic clarity, a concentration of detail unnecessary had the purpose merely been to demonstrate the broad outlines of Mahler’s works to potential interested parties. These transcriptions were meant to spread the word, reaching out to audiences during a time when performances of Mahler symphonies were still rare events.
Most piano duet arrangements were meant for the home rather than the concert hall. When you sight-read orchestral reductions at the piano, your physical involvement with the material “fills in” the missing instrumental color. Even with skillful four-hand “de-orchestrations” like Max Reger’s of the Bach Orchestral Suites, listeners run the risk of “registral fatigue”. In the main, the Speidel-Trenkner piano duo circumvents these limitations through canny pianistic means. In the C major Suite’s Forlane, for example, the oboe’s hornpipe-like melody bounces on a featherweight accompaniment.
A superb recording of the Bach's Orchestral Suites transcribed for a piano duet. It makes a great change to hear these excellent pieces of Bach played as a piano duet to the standard orchestral version. I am absolutely delighted with it and it is great that I now have both the original orchestral version (complete) and this complete version too. For anyone who enjoys piano transcriptions of orchestral works, this recording is highly recommended.
If you know and love the Brandenburgs, seriously consider listening to these renditions for piano duo. In the imagination place yourself in the days before recording; hearing these peices in that way will give an idea of what it must have been like to know Bach, to want to hear Bach, to have the muscial skills to play Bach, but have no chamber orchestra at your disposal. A piano or two would do, if you had Reger's transcriptions. Why wait years for the next concert, if you could play them today? And because Reger loved Bach each piece has an air of homage.
