SOPP437: How could practice in writing make playing easier?

This question was sent by May, who is our Total Organist student. And she writes: Hi Vidas, Thank you again for addressing to my concerns in details! I have not had the time to spend on the 3 to 4 rhythms yet. In fact, I had to put the sight reading courses aside in order to focus on the harmony (which has been taking 1.5 hours each day from my practice time). I simply don't have the time for writing out the chords beforehand (it would have taken me at least another 45 minutes each day to do so). In your week 11 video, you said it would be easier if we write down the chords before doing the hands on practice. How could practice in writing makes playing easier (for we are not looking at our chords when we play the harmonization anyways)? And, she has questions on the week 11 harmony video and exercises.... 1. When you demonstrate exercise 1, you say aloud each chord (and how it connects to the next chord). For the first 3 chords in the 2nd half of exercise 1, I think I hear you say "subdominant". Should they be tonic? 2. In exercise 8, the 2nd note (A) in measure 3 belongs to tonic chord, and the 3rd note (D) belongs to the subdominant chord (See attached). They are apart by a 4th. In what way should they be connected using our rules? Thanks in advance for your help. May
