Utilize slow and gentle melodies with smooth transitions between notes, creating a contemplative and somber atmosphere. Explore using minor chords and soft dynamics to enhance the emotional depth of the composition. Experiment with pauses and silences to allow for moments of reflection within the music. Consider incorporating subtle variations in tempo and phrasing to convey a sense of introspection and longing in the melody.
