While studying the 2nd movement of Beethoven's Sonata Op.90, I found these appoggiaturas in bars 28-29.
This is the Henle edition (which I find to be one of the most reliable editions for Beethoven); the appoggiatura can also be found in the 1815 first edition (see here).
Based on my knowledge, I thought the two bars would have to be played like this
but in all major intepretations I listened to, the F and A are played as acciaccaturas respectively on the E and G (here is an example).
Does anyone know why everyone performs it as an acciaccatura? How did Beethoven intend the two embellishments?
