where can i hear trumpet notes online so i know if i am getting high f or e

lol.....i dont know of any sites but you should get a chromatic electronic tuner. i`ve got one that spans 8 octaves, its by korg, called the CA-30 or something like it. its great if you play guitar too. its like 20 bucks but i got it for christmas. what you do when your playing really high is play into the microphone of the tuner and see the highest note it puts out. remember though that the note according to the Bb trumpet is actually 2 half steps(one whole step) higher because the trumpet is tuned in Bb. so if the tuner says f. in trumpet language you played a g. but i only count the note if i can easily recognize the it by playing the note i think it is an octave lower and then an octave lower than that and if it matches up it counts.
