If you look at the image below, you'll see that the 3 treble bars and the first two bass bars accord with 3/4 time, but the last bass bar to my mind does not. I also do not understand where the rest is supposed to be played when it is directly over a note, before that note or after it?
In order to calculate if a bar accords with 3/4 time then it follows that one beat equals one quarter note and there are to be three such beats in a bar. If two quarter notes equals the same amount time as a half note, then it follows that in the bass clef there are 6 beats, which is three too many. I still don't understand where the rest is supposed. Let's also break this down in terms of time. The tempo is set at 42 quarter notes per minute. 60/42 = 1.42. Hence two quarter notes should be played 1.42 seconds apart and two half notes at 2.84 seconds apart. Each bar then should last 4.26 seconds. The bar in the bass clef would last 8.52 seconds.
Imagine there are three musicians. One plays the top line - all the treble clef notes. Another plays all the bass clef notes that have downward pointing stems. And the third plays only in the third bar (that's all that is written for him) and he plays a rest followed by a D note for two beats. That's it. It will sound exactly as written.
Reasoning is that in the third bar, there are three voices. It can be played by one person on piano. It could have been written with that D tied across 2nd and 3rd beats, with the B written in under the second D note - the tied over one. The vast majority of music which effectively splits into three (or more) parts temporarily is written this way for piano.
You effectively have two separate lines happening in the bass clef in bar 3. On the first beat the B sounds by itself. On the second beat the D is added while the B is held. On the third beat the B is played again while the D is held.
