AVA220: It seems to take me ages to learn a hymn

This question was sent by Jan, and she writes: Dear Vidas, Thank you for asking how my practice is going today. Today I am struggling with hymns. I am not very competent with the pedals. I practice separately...pedals, RH, RH and pedals, LH, LH and pedals, RH and LH, RH LH and pedals. I also write in the pedaling and fingering. It seems to take me ages to learn a hymn; especially as playing a hymn on the piano is very easy. Perhaps I need to do more slow practice and perhaps I need to do more separate practice rather than playing the hymn together over and over again. On a more positive note...I have been playing in church for a year now and my playing has definitely improved. I am very pleased. It has been worth all the hard work. Thank you for your help over the last year. Kind Regards, Jan
