Answer the questions briefly:

What are the other sounds that bring delight?

The other sounds, apart from that of insects in a garden, that bring delight are the sound of the sea waves and the chirping of birds. The author describes that these three sounds are capable of inducing a pleasure in humans that is much beyond that caused by musical instruments. Since they are so organic and natural, they seem to be in harmony with our breath and blood as well. These sounds also remind man to be happy that he is alive.
