Ebichan, my vocal instructor, revealed his policy about his concert:

Today I've got my 4th vocal lesson. Talked and talked after lesson. His 3rd concert will be held on Sept. 1-2 within Saitama City, where he is working for a school as a music teacher. He might sing 10 songs and entertain audience by Emcee. In previous concerts pianists backed his singing, but this time he will use Karaoke, because pianists did not like to play notes from too wide range of genres. He wanted me to find my original approach to singing.

Lesson: 1. Vocal training with abdominal breathing. 2. Reading notes. 3. Singing at first glance.

New song: Ebichan gave me "Begin The Beguin". I am expected to rewrite it into lower key for myself. In September we will have lessons on Fridays before my band's weekly practice.

Evaluation: Ebichan highly appreciated my challenging attitude to music and promised I would become a good singer. He also offered me to do whatever I would like to. So we might make various experiments just like  chords and chord progression.
