If so, I have an idea for you - 100 day scale and arpeggio challenge. Here is how it works:
At the beginning of each day organ practice, you simply play one major and one minor scale and arpeggio with the same number of accidentals for one week. Then on Week 2, you practice G major and E minor. On Week 3, play F major and D minor. Then D major and B minor, B flat major and G minor and so on.
In other words, you always play a pair of major and minor scales and gradually increase the number of accidentals until you reach 7 sharp and flats.
Play these scales and arpeggios 3 times every day.
Here is how can test the results of this challenge:
Pick an organ piece that you have never practiced before and play it once on Day 1 and on Day 100. Do not play it anytime between these days. The results on Day 100 might surprise you.
