... my knowledge of music is rather limited?
I know how to read music, although just about, and dabbled in guitar and recorder in my distant youth.
One issue is that I learned abroad so I am a Do Re Mi, rather than C D E kind of woman. I can learn but it's not natural so it'll be a bit tricky until I get used to it.
Apart from the cost, and the lack of local teachers, I am thinking it may be best for DD to learn recorder with me (already knows the basics), then go the local music service at the weekends to practice with an ensemble.
Does that sound feasible to you, o experienced musical people?
