When I started playing Rumba, it was so easy for me to do the rhythm. I must be latin ????? I still have no vibrato.

I have tried to do Andante in C's bits, but I sound like a strangled cat at best. Andy is right in that you have to have a good straight tone first, but will I EVER have a vibrato?
Will be doing the Grade 5 in july after deferring from march because my Dad had to go into a nursing home/ It was to be a busy month clearing his house in January, and then thank goodness I defered, because he had 3 heart attacks in the last 10 weeks. He is OK now, but it has been a busy time with no practise.
