I focused on the sha sha ten but I broke my arm so I could not participate the concert. But, I improved when I memorised the lyrics for the sha sha ten part since the sha sha ten note changes. And I also got faster to do the sha sha ten before I broke my arm. I still cant keep the rhythm. Which I play the beat and the notes fast. To stay on the beat I think that I should stayed on the beat.
I think next I should write the homework assignment sheet when I practised. Since I forgot to return it. Also I think I should of practised more time on the koto. I was a little lazy and did not do some practise for 1 hour like every day, instead I practiced for 15 or 20 minutes since I was also very busy.
I could not participated on the concert since I broke my arm. But, I think that in the video of the concert the beat was getting fast and slow some parts. I think that I will work on the beat since it is a common, and very hard mistake to improve. I also think that at the end a few people tried to stand up and bow but some did not and everyone sat down and bowed. So, I think that next time if I was going to go on stage, I will make contact and remind the team the plan. But I also think that there were not many koto mistakes for a note. And also I did not hear a squeaky or a unpleasant sound while the concert.
