notes for the trumpet w/o pressing the 3 valves are -
low C
G (2nd line on the staff),
high C (3rd space on the staff),
high E (4th space)
High G (above the 5th line)
etc...
check your pitch with any standard instruments like keyboard or tuned guitar or tuner... Bb instruments (trumept, clarinet, tenor sax, soprano sax etc) are 2 semitones higher than the concert pitch..
example: - Bb on piano/keys is your C on Trumpet,
C on piano... - is your D ...
