I’m adding a list of cello-related blogs, most of which I found through Guanaco’s Cellomania blog. He has an enormous list of over 120 blogs by people who play the cello. I’m not stealing/duplicating/mirroring his entire list; I’m looking at them and trying to list the ones which have frequent posts about the cello and/or classical music.
And through Cello Chat I found Emily Wright’s recently-established Stark Raving Cello. Emily’s a cellist and teacher in California who is trying to decide whether to turn her 60-page book into the 200-page book Oxford University Press is looking to publish. If you buy books on how to play the cello, you might want to give her some feedback.
