德國音樂學校協會主張『最新的鋼琴教學法是讓鋼琴適合於多種變化的教學形式，將它當成團體授課的樂器。』，海布特鋼琴教本依此設計，全部的音樂都以適合『雙人彈奏』而編集，每册上半年，爲兩年的鋼琴學習所擬定的。在此期間所敎導培養出來的各種能力，無論是彈奏、技巧及合奏能力，都將能順利地銜接往後的鋼琴學習課程。

"The latest piano teaching method is to adapt the piano to a variety of different teaching methods, and treat it as an instrument for group teaching."
──From the piano teaching plan of the German Music School Association

This elementary piano textbook (a full set of four volumes) derived from songs and strums, regardless of content or structure-the same as every good piano textbook that has been published-is a rigorous and complete system of its own .

However, the basic difference between it and other piano teaching materials is that all the music in this set of teaching materials is compiled for "dual playing". In other words, its compilation is based on the premise that most of the pieces can be played alone, but also in ensemble with each other.

In order to comply with this tutorial principle, its combination and changes are compiled through multiple designs. Specifically, the characteristics of this textbook are as follows:

―Adjacent pieces can be played together.

―Some songs are suitable for Canon's playing.

―Practices such as fingers, timbre, rhythm, etc. are all written to smoothly import the next song.

―The first part and the second part of the four-handed bomb have the same difficulty.

―For tunes with accompaniment, consider adding a recorder.

―As for the "visual notation practice" and "searching for the keys" unit, the instructor needs to introduce the content to the students in various ways.

In addition, this set of textbooks also incorporates solo music written specifically for personal performance. The author believes that this is necessary for students in group classes, because students must practice at home alone and have fun.

In this regard, this set of materials will also be a good set of supplementary materials for learners who accept individual courses. However, in any case, the students who use this textbook have an advantage-because they have long-term "duo" opportunities, they can all have excellent joint playing skills. On the contrary, for a student who continues to receive individual lessons, he roams in the weekly piano lessons instead of enjoying and experiencing the fun of "playing the piano together"; then, in terms of cultivating the joint playing ability, he must Is lacking! !
