The piano is hailed as the king of instruments. With its wide range and beautiful tones, the use of twelve-tone equal temperament allows for great freedom in modulation, counterpoint, and harmony in the world of music, showcasing virtually all languages, grammar, rhetoric, and more.

Why do most music learners choose to play the piano? It's because the piano is the best teaching tool in music education. Its comprehensive performance capabilities determine its crucial role and value in music education.

Whether in sight-singing, ear training, vocal, instrumental, harmony, or composition, the piano, as a compulsory course in various music majors, has become a convention in music schools worldwide.

During the process of learning the piano, children can study sheet music, learn playing techniques, and acquire numerous music-related knowledge.

Furthermore, they can develop three essential abilities: attention, coordination, and confidence. From any perspective, these three abilities are crucial for a child's healthy development.

How do these abilities develop and improve as a child's piano learning progresses? Mr. Baldwin, an American music teacher, provided a concise and insightful analysis:

1. Reading a single-line musical score, playing a melody with a single finger: Training a child's general attention.
2. Reading a single-line musical score, playing a melody with the right hand comprising two or three notes: Training a child's stronger attention.
3. Reading a two-line musical score, playing different parts with both hands: Training a child's high attention and coordination.
4. Reading a two-line musical score, simultaneously coordinating the movements of both ears, arms, fingers, legs, and feet to play a piece—training a child's highly precise attention, coordination, and, consequently, fostering confidence.

From the perspective of instrumental specialization, the piano itself possesses several advantages:
1. Besides being the best accompaniment instrument, the piano is also the best solo instrument.
2. Rich expressiveness, with dynamics ranging from ppp to fff, capable of producing various tones and expressing a wide range of emotions.
3. Broad range, with 88 keys, covering nearly all the pitches used in musical activities.
4. The piano serves as the foundation for learning other instruments, especially keyboard instruments like the accordion and electronic organ.
5. Learning the piano forms the basis for acquiring other music-related knowledge, including music theory, harmony, composition analysis, and music creation.
6. Learning the piano is one of the best means for early childhood music education, and many musicians started with piano lessons.
7. The piano is frequently used in classroom teaching, vocal accompaniment, dance accompaniment, etc., making it the most commonly used and effective musical teaching tool.
