Final answer:
The statement is False. Studying textbooks alone is not sufficient for learning harmony in music.
Step-by-step explanation:
The statement, "He learned harmony by studying textbooks," is False.
Harmony is a musical concept, and while studying textbooks can provide theoretical knowledge about harmony, it is not sufficient for actually learning to apply harmony in practice.
Learning harmony typically involves studying and practicing with a musical instrument, such as piano or guitar, and understanding various musical elements like chords, scales, and progressions.
To truly learn harmony, a student would need to apply the knowledge gained from textbooks and engage in practical exercises and hands-on experience with an instrument or in a musical ensemble.
