The opening 4-note motif as the “Fate Motif” and how it unifies entire piece?

Question

Beethovens Symphony No. 5, and do you know who Beethoven influenced 1975 and on?

Answer 1

We might need a few more details <g>

If you're talking about Tchaikovsky's 4th Symphony, the "fate" motif is more than four notes. But it can be heard throughout the first movement, then it rears it's ugly head again in the last movement... very powerful piece.
