Weighted Keys vs. Spring Action
Piano students preparing for Trinity or ABRSM examinations often struggle when switching from a lightweight electronic keyboard to a real acoustic piano. Understanding key weight is essential before making your purchase.
1. Digital Pianos (88 Graded Hammer Standard Keys)
A digital piano (like the Yamaha P-125, Yamaha P-45, or Casio CDP-S110) replicates the physical hammer mechanism of a grand piano. Lower notes feel heavier, while higher notes feel lighter, building proper finger strength and dynamic expression.
2. Portable Synthesizer Keyboards (61 Touch-Sensitive Keys)
Arranger keyboards use plastic spring-action keys. They are lightweight, budget-friendly, and feature hundreds of rhythm styles, accompaniments, and synth voices.
