"Trumpet Cornet" is a placeholder name for an 1878 song performed by Thomas Mason in a tinfoil phonograph.
The song was recorded in St. Louis, at a hat store named Steinberg & Co, on June 22, 1878. It used a tinfoil phonograph, which had been invented by Thomas Edison in 1877.
The recording also featured the nursery rhymes "Mary Had a Little Lamb" and "Old Mother Hubbard".
"Trumpet Cornet" is a rather short instrumental song set to the tune of B-flat. Its instrumentation only consists of Mason's cornet playing.
