This lesson will teach you how to produce sound on the trumpet. The note chosen for this mission is C 3, located on the first supplementary line below the staff. To play this lesson, always breathe through your nostrils on three counts and through your mouth on the fourth beat. Emulate the pronunciation of the consonant “t” with the vowel “a” (tah), to attack the note C. Keep the feeling of the vowel “a” in your throat and tongue, seeking an open and generous sound. Make each note last four beats and obey the pause that follows, in four beats of silence. Instead of remaining inactive and distracted during breaks, always be alert! Count each beat, paying attention to the accompaniment and the recorded example. Every now and then, play in unison with the reference, rather than repeating it.
