Trying to compose a melody for a trombone

At least one each of only the tonic, supertonic, mediant, dominant, subtonic, and leading tone. Make note of which scale degree(s) should not be included in the melody.

Use a Minor key signature, Quadruple meter, and structure (form) that is preferable

Include bar-lines, dynamics, and articulations,

Do not need to use an anacrusis.

The score should have one phrase per system for a total of four systems.
