I had 2 lessons with Helen Krizos and one with Megumi Masaki in the 1st week and 3 with Martin Roscoe in the 2nd. All were excellent but I think I particularly benefitted from having 3 lessons from Martin and playing in his 2 workshops, where he gave me some extra help. He was very exacting but also kind and I felt I had to raise my standard for him. It was quite different for me this year as I've usually had teachers I know well for the last few years, but they weren't there this year and I had to try new people, which I think was good experience for me.
Martin was my teacher's teacher.
