SOPP422: he harmony course is like a brain exercise

This question was sent by May, and she writes: Thank you Vidas for sending me this video. I didn't have a chance to watch it yet. The harmony course is challenging enough for me. It's like a brain exercise. With the S-D transposing sequences, I have to first figure out what key it lands on at a major 3rd interval. Then which key is its subdominant and which key is its dominant. I took a long time before I could run through each of the 6 sequences from C major, a minor, Bb major and g minor three times without making mistakes. Today, I just finished watching the week 7 video. I think I have to postpone the sight reading course until after I finished with the harmony course (hopefully in 6 weeks). Otherwise I would not have time to prepare or the music in lent. Actually, how much time we should be spending each day to work on these exercises in order to accomplish the improvement you expect? I guess I can use the pedals with the week 7 exercises. Perhaps I should say I have to use pedals for the bass because it's impossible to reach all 4 notes by hands only in many cases. Thanks again for your advice. May
