As I have previously mentioned, Merlin, the app I am using to identify birds in my recordings, provides spectrograms for each bird call. I plan to use this to inspire my graphic score that will accompany the final version of my composition.
When researching bird calls I have also been paying attention to the spectrograms that it provides. Bird such as the Eurasian Wren
and Coal Tit, which have quite melodic calls have swooping lines to represent the pitch and speed of their call, the image for the blog shows the call of the Coal Tit. Versus a bird such as the Bank Swallow, whose call sounds more like a buzz than a melody, is represented by thicker blocks of colour.
Depending on the focus of each section, I plan to draw certain bird calls thicker and more prominent, to represent where they sit in the mix of the recording. I may choose different colours for different bird, to easily layer different styles of calls over one another. I will attempt some drafts of certain bird to see if there is anything I should change or add for my final version.
