It's easy enough to count if you listen to the strings. Take the first verse.
The first 'I' of 'I... I who have nothing' is on the first beat of the bar.
The strings rest on the first beat of that bar, then play eighths on beats two and three, with a quarter note on beat 4. On the next bar, the strings rest on beat one, play eighth note triplets on beat two, then straight eighths on beats three and four...
Code:
| 1 2 3 4 | 1 2 3 4 |
| - 2 and 3 and 4 | - 2-e-and 3 and 4 and |
