Crotchets in Ap

..

In Ap three last two-note chords of the lower voice in the R.H. are crotchets. After the previous (from the beginning of bar 47) five semiquavers, it means an attenuation of articulation (in this context semiquavers imply staccato, whereas crotchets – tenuto or legato), which corresponds to the final diminuendo.
