76 Keys vs 73 Keys Compared
Number of Keys
The Yamaha YPT-W320 features 76 full-size keys, while the Korg Kronos 3 offers 73 keys. The Yamaha provides three additional keys, extending your range on both ends of the keyboard. This extra span can be useful for playing wider chords or accessing notes that fall outside the standard 73-key layout. The Korg’s 73-key count is a common configuration for music workstations, balancing portability with a comprehensive range. For most beginner tasks, both layouts are sufficient, but the Yamaha’s slightly wider span gives you more room for extended passages.
Key Action
Key feel differs significantly between these two instruments. The Yamaha YPT-W320 uses touch-sensitive keys, meaning volume changes based on how hard you strike the key. This is ideal for learning dynamics and basic expression. The Korg Kronos 3 employs RH3 Weighted Hammer Action keys, which simulate the physical resistance of an acoustic piano. This weighted action provides a heavier, more realistic feel, suitable for advanced technique and classical training. If you prioritize authentic piano resistance, the Korg is superior. For lighter, responsive playing, the Yamaha is better.
Form Factor
Portability is a major differentiator here. The Yamaha YPT-W320 is designed as a portable keyboard, weighing only 11.4 pounds and measuring 45.2 inches in width. It is easy to move and store. The Korg Kronos 3 is a substantial music workstation, weighing 55.3 pounds and measuring 49 inches wide. It is built for a stationary studio setup rather than frequent transport. The Yamaha is clearly the better choice for students or gigging musicians who need to move their instrument often. The Korg is intended for a fixed location.
Target Audience
These keyboards serve different user groups. The Yamaha YPT-W320 targets beginners, featuring educational tools like Keys to Success and Touch Tutor to help you learn songs and dynamics. It includes built-in songs to guide practice. The Korg Kronos 3 is a professional music workstation aimed at producers and serious musicians. It includes nine sound engines, an 8-inch Color TouchView Display, and a ribbon controller for complex sound design and performance. The Yamaha is for learning to play. The Korg is for creating and producing music.
Included Accessories
What comes in the box varies by model. The Yamaha YPT-W320 includes a music rest and a power adapter, providing everything needed to start playing immediately. The Korg Kronos 3 data does not list specific included accessories, so you may need to purchase stands or adapters separately. The Yamaha’s inclusion of a power adapter ensures you can use it right away without searching for a compatible unit. For a complete out-of-the-box experience, the Yamaha offers a slight advantage with its bundled essentials.
