How many violins and cellos did Antonio Stradivari make?

Around 1,000, yet only 625 are still in existence.

it depends on if you are playing it piano or forte . 82 to 92 dB

four strings are on a violin and a cello.

Im pretty sure there is 5 oil, lion, in, on, and no

Yes only few very very rare though. much rarer then the full sizes as they did not make many its highly collectable if original
