The timing is 4/4, so first the E-B-G chord is held for 1+1/2 beats, then the tied EBG chord is held for a combined 1 beat, I think, but then what does the little squiggle in front of the fourth lower G note mean? My best guess is it’s a F sixteenth note so you hold it for 1/4 beat, and the third EBG chord is also made of sixteenth notes, but honestly I’m not sure.
Ah, the counting of this measure is easier than you think. That small note is just a grace note. A grace note is a note that is played very fast right before the next note. For example, this
is in reality just this:
So, to address you counting issue, let us count the eighth notes as 1 + 2 + 3 + 4 + in 4/4 time. So we can count your music like this:
I hope that helps! Let me know if you need any extra clarification
That's a grace note. The slash indicates that it's acciaccatura so it's pretty much as brief as you can make it with the note borrowing from the duration of the G that follows it.
I'd start by not even playing that acciaccatura - a grace note which has no real time value of its own. So the count for the main notes would be 1 & 2 & 3 & 4 &.
When the timing is good, think about the acciaccatura as a small mistake, just as you were supposed to play the & after beat 3. Thumb on the F♯ for a brief moment, sliding onto the G as you play the D♭ and E♭ maybe with ring and pinky (fingers 4 and 5).
