Help me on this guy: P.I Tchaikovsky?

i want to know whats his famous holiday music and war music

holiday music ? - Nutcracker Suite, Swan Lake Suite

war music: 1812 Overture

Holiday music - The Nutcracker Ballet
War music - 1812 Overture

His most famous "holiday" music that I can think of is naturally, "The Nutcracker" ballet.

War music: "The 1812 Overture".

I don't think his "March Slave" actually depicts war(s), but is certainly reminiscent of it.

The "Romeo and Juliet Overture Fantasy" is not war music in its totality, but its depiction of the dueling scene is musically very graphic.

You show your ignorance by this question. Just listen and learn instead of listening to garbage like rap.

His war music really is an overture. Its title is 1812 Overture (or in full Festival Overture 'The Year 1812'), in commemoration of the Russian's victory over Napoleon forces.

There were no specific 'holiday music' in his forte, but The Nutcracker has become the staple during Christmas weeks and New Year.

Holiday music: Scene from Swan Lake
