The other Jewels of the Crown voice doubts about Tansen's musical ability because:
1. They think that Tansen is only capable of imitating the sounds of birds: This indicates that they believe Tansen may lack originality or depth in his musical talents, possibly viewing his skills as limited to mimicry rather than true creativity.
2. They notice that Tansen is getting all of the emperor's attention: This suggests that they might be envious or resentful of the favoritism shown towards Tansen by the emperor, leading them to question his musical abilities as a way to diminish his reputation and influence.
3. They think that the emperor has no knowledge of or taste in music: This implies that they doubt the emperor's judgment in recognizing Tansen's musical talent, indicating a lack of respect for the emperor's musical discernment and preferences.
