My 9 year old 4th grader soon to be 10 years old plays viola(1 year), flute(1 year),piano(2 years),sax(alto/soprano 4 years{since kindergarden). My sister in-law argues it is too many instruments. I defend my daughter on the basis thaT you do not put a viola or piano in your mouth(embouchure) and flute is similar(fingering) to sax and again you do not put it your mouth(so it should not effect her main instrument sax). Now my daughter wants to play the french horn. She would get this for free from the school. I flat out refused. I know the band director quite well as she is my daughter'sa flute teacher. Band director says she would be good at french horn cause she has a good ear. She played sax in summer band in 2nd grade and flute in 3rd grade. This is her 1st year in the school band(she is playing alto for xmas concert-flute for spring concert). They would not let her play in school band from grades 1 through 3 cause of her age. She did sit in on the sax quartet for xmas concert last year{her sis played tenor and I sat in on bari}.I feel woodwinds/brass should not be mixed in elementary school due to potential embouchure problems. She plays sax quite well and I would not want to ruin her sax playing. I invested a good deal of money into her sax playing(a Yani A-901 and a SC-991). She plays quite well w/ the sax trio we have.(she plays alto{sometimes sop},her older sis tenor and myself baritone).I would appreciate some feedback on this from the forum. Any examples of brass and woodwind players at this level or is it just a plain BAD IDEA!!!!
