German-born, Canadian composer, Hildegard Westerkamp is able to "push the envelope" in many of her compositions. After she finished her music studies, she became interested in the study and composition of environmental music. She is a composer, educator, and radio artist. Her compositions include urban and rural wilderness soundscapes, along with children and adult human voices, with noise, silence, music, media sounds, and sounds of different cultures. There is music in our environment every day, Westerkamp helps us realise how that music can be recorded to inspire our lives, and make us more aware and appreciative of the creative, life-giving nature of our environment. I've chosen to share two of her works one a YouTube, the the other an audio sound clip, called Harbour Symphony, consisting of boathorns, which you can listen to here.
