I can't believe I'm saying this because until DD was born I was 100% convinced perfect pitch didin't exist! However, my DD (age 7) is proof otherwise and has been offered tuition on trumpet, french horn or trombone.
I have concerns about her size and development for any of these really, but DH (also claims to have perfect pitch) tried clarinet as a child & could not get to grips with a different note coming out to the one he was reading & got very frustrated and gave it up.
As a C instrument player I have no experience & would love to hear others thoughts! Can perfect pitch & transposing instruments live in harmony?? [please forgive the unintentional pun]
