Most of the difference between trumpet, cornet and flugel its due to the aproach and sound concept of the player and also because of small variations on technique, obviusly there at least in the case of trumpet and flugelhorn there are always little nuances in the sound that are inherent to each instrument, for instance you could make a trumpet sound very mellow using slower air stream and articulating in a certain way but It never sounds identical to a flugelhorn and the opposite its also true, but in the case of trumpet and cornet they are in my opinion essencially the same instrument.
@@veselkamileva8752 Yes they are all different instruments but its not very dificult to make them sound similar, for instance concerts that are originally played with the cornet like the Carnival of Venice are nowadays played succesfully by great trumpet soloist like Rubén Simeo, Nat Adderly played long cornets his entire career he could sound identical to a trumpet when he needed the same with Warren Vache who playa both long and shepherds crook cornets, in the case of flugelhorn and trumpet the difference in tone and tuning of the instrument are bigger, but with slower air, low volume and a certain sound concept you can make a trumpet sound very closed to a flugelhorn and also its true that on the hands of inexperienced players its very frequent that the flugelhorn sounds very closed to the trumpet tone.
