Answer:
To make your lead singer happy with the song's melody, option (d) Adjust pitches and rhythm to make the melody more interesting would be the most appropriate approach.
Step-by-step explanation:
Here's why:
a) Changing the tempo to make the song faster (option a) would alter the overall feel and energy of the song but may not necessarily address the lead singer's issue with the melody itself.
b) Changing the meter from 4/4 to 3/4 (option b) would change the rhythmic structure of the song but might not directly address the lead singer's concern about the melody.
c) Changing the accompaniment to make the melody stand out less (option c) could potentially solve the problem, but it might also diminish the impact and presence of the melody. It's important to maintain a balance between the accompaniment and the melody.
d) Adjusting pitches and rhythm to make the melody more interesting (option d) directly addresses the lead singer's concern. By exploring different melodic variations, incorporating catchy hooks, adding ornamentation, or experimenting with rhythmic phrasing, the melody can be enhanced and made more appealing.
