How many symphonies did Tchaikovsky write?

Answer 1

Tchaikovsky wrote six symphonies, and some musicologists consider his "Manfred" to be a symphony, but most see it as a symphonic poem. Tchaikovsky died ten days after the premier of his last symphony, #6 in B minor. Fragments of other started and abandoned works were cobbled into another "symphony" many years later, but it is only Tchaikovsky's actual writing here and there, and got a poor critical reception - it is mostly forgotten today.

Answer 2

Tchaikovsky wrote 7 symphonies and 4 orchestral suites.
