No, music lessons never helped in my experience. Junior school (70s) consisted of wrestling (not literally) with a recorder which I never got to grips with and being shunned from the choir due to having a voice like Johnny Rotten. We were put in a group called 'The Groaners' and spent choir practice time by doing drawings instead. Secondary school (80s) was no better. We did the usual 'this is a stave' , 'Mozart, what a guy' etc but my main memories are designing LP covers and sometimes bringing records in. One chap brought in a tape recording off of the TV of dismal, yanky, puppet nonsense Fraggle Rock that for some reason we listened to for 20 minutes before the teacher (who was a geography teacher) restored our sanity and whacked some Motown on. Typing that has just reminded me that for one whole year we never had a music teacher, it was always a PE teacher or whatever. Sometimes, we never had a teacher turn up at all. Dropped music after the third year when options came up because it was just a doss twice a week.
The only instrument we got our hands on were glockenspiels for about four lessons very early on in the first year there. Can recall infuriating our teacher by our consistency in making the little wooden balls on the end of the beaters fall off and roll across the classroom. He was going apoplectic, how we laughed. Until we got to school the following morning to be told he'd died of a heart attack overnight. Sorry, Mr Edwards, though I think your heroic boozing and 2 lighters a day smoking habit may have been contributing factors as well.
