found: Grove Dictionary of American Music, 2014:(Ecomusiology, or ecocritical musicology; the study of music, culture, and nature in all the complexities of those terms; considers musical and sonic issues, both textual and performative, related to ecology and the natural environment. The 'musicology' of 'ecomusicology' is more precisely what Seeger propounded as including what today are historical musicology, ethnomusicology, and other related interdisciplinary fields. On the one hand, this encompassing sense results in ecomusicology as an implicit umbrella term that may bring together fields that to not usually interact. On the other hand, such broadness allows scholars considerable flexibility to combine diverse disciplines in ecocritical studies of music." Ecomusicological approaches to considering human musical systems, traditions, perceptions, and compositions include studies of influence, mimesis, and/or reference of the natural environment using textual, sound, and/or extra-musical means. Such studies have come primarily from ethnomusicology and historical musicology)
