To delight of music lovers around the world Thomas Edison invented phono in 1879?

That sentence has a few errors! Here's a corrected version:

To the delight of music lovers around the world, Thomas Edison invented the phonograph in 1877.

Here's why the original sentence needed fixing:

* "phono": This is not a complete word. The invention is called the "phonograph".

* 1879: The phonograph was actually invented in 1877, not 1879.

* "invented phono": This is grammatically awkward. It's better to say "invented the phonograph".
