When Smetana composed his Piano trio in the autumn of 1855 it was an act of catharsis to recover from the death of his four-year-old daughter Friederike. This highly emotional work was also his first large-scale piece of chambermusic. Its first public performance in December 1855 was regrettably not a great success and so Smetana embarked on a protracted process of reworking it. By the late 1850s it had reached its current form. Smetana always liked toperform it but only found a publisher for it in 1880 when one of his pupils invited the Hamburg publisher Hugo Pohle to a performance at short notice. Smetana specialist Milan Posp Å¡il has based this Henle Urtext edition on thefirst edition by Pohle but has also drawn upon the earlier sources. This has enabled him to iron out numerous inconsistencies found in the first edition.
