Piano types depend on technology and sound source from "summary" of Acoustic and Digital Piano Buyer by Larry Fine
Piano types can be categorized based on the technology and sound source they utilize. The two main categories are acoustic pianos and digital pianos. Acoustic pianos produce sound through hammers striking strings inside the instrument. There are two main types of acoustic pianos: grand pianos and upright pianos. Grand pianos have horizontal strings and a larger soundboard, while upright pianos have vertical strings and a more compact design. Acoustic pianos are known for their rich and resonant sound, as well as their touch sensitivity. Digital pianos, on the other hand, use electronic technology to replicate the sound of an acoustic piano. They often have weighted keys to simulate the feel of an acoustic piano, and they can produce a variety of sounds in addition to piano tones. Digital pianos are more portable and versatile than acoustic pianos, as they can be easily connected to other devices and have features like headphone jacks and recording capabilities. Hybrid pianos combine elements of both acoustic and digital pianos. These instruments use acoustic piano components, such as strings and hammers, along with digital technology to enhance sound quality or provide additional features. Hybrid pianos offer a compromise between the traditional sound of an acoustic piano and the modern capabilities of a digital piano.- The type of piano that is best for a musician depends on their specific needs and preferences. Acoustic pianos are ideal for those who prioritize traditional sound and touch, while digital pianos are better suited for those who require portability and technology features. Hybrid pianos offer a middle ground for musicians who want a blend of both acoustic and digital capabilities.
