I usually know what it means when a note has both a stem pointing up and another pointing down (What does this note have a stem pointing up and another pointing down?), but what if it has something like a staccato in one voice, while something else (e.g. legato) in the other? In the example below, should I play the second to last note in the bass clef as a 16th-note staccato or hold it as a regular quarter note?
(Excerpt from the 2nd movement of Beethoven’s Sonata No. 2, Op. 2/2)
Also, is there a general rule for playing this (like “hold down for the full duration of the longer note value”, which seems to usually be the case), or is it just contextual, or perhaps a matter of interpretation that’s up to the performer?
