I don't actually have one. Normally I would spend fifteen minutes warming up by playing some songs by heart or from the Real Book. Then I would explore some difficult songs. For example, I tried playing songs by Wayne Shorter for a while or making easy songs more complicated. I'm not very good at practicing e.g. scales in a creative way or 2-5-1 progressions. I prefer to practice those in the context of a song.
Sometimes I try to transpose a song by heart into a different key. But even better for me is when I am forced to do so. For example, at our band recently I brought up the suggestion of playing You Are The Sunshine Of My Life. I only knew the song in C. But the original is written in the key of B. So we decided to play the song in B. After playing it twice we transition a semitone higher to C at the end. In the key of C, we play only the A part twice, followed by a little outro. I can now play the song well in both keys.
By nature, I am quite focused on variation and doing something different and new. Repetition and stiff practicing are not so much my thing. However, the main reason why I cannot practice systematically is my wife's health situation. For that reason, I cannot take my time to play piano daily. I have to make more use of the small half hours or less that arise, sometimes unexpectedly, depending on the necessary daily routines in helping and supporting my wife.
Because I am firmly motivated to complete Gjermund's program, the lessons keep me focused. However, every now and then I want to get away from the pressure and do something completely different. For example, I want to learn more about playing the songs by Wayne Shorter. Consequently, I spend also some time to this kind of music in order to fulfill my need for exploring new things.
