PTNA starts selling the materials to support analytical study of required repertoires of the 2011 PTNA Piano Competition. There are three volumes; for elementary grades (A2, A1, B & duo), intermediate grades (C & duo) and for advanced grades (D, E, F ).  The analytical descriptions are written by 8 professors and music scholars; Tetsuya AKIYAMA, Yasuhide ITO, Koichi UZAKI, Katsuhiro OGURI, Osamu KAZUKI, Ichiro KANEKO, Takashi MATSUO, Masakazu YAMAMOTO. 

Besides, to provide basic knowledge about the analytical study, the special instruction is available on the volume 1 for the pupils and teachers of grade A2 (around age 4-5). Mitsuyo ESAKI, a member of PTNA board of trustees, emphasizes the importance of analyse from the earlier stage, as it would help children nurture the structural analysis and esthetic understanding of music. The scores are provided with colors and short descriptions so that children can understand the musicals form easily.

She explains that "it is very important to know that every phrase is not a mere continuation of notes. Every note has some meanings within the phrases and I hope this score would help them find it out and create music by themselves." 

ESAKI has been served as the chair of Selection Committee of Required Repertoires for over 35 years, and has received TOYOTA teacher's special award in 2000.
