Keybird Instruments is developing a lightweight acoustic piano to help piano enthusiasts play with their preferred sound (acoustic) with practicality and price comparable to that of digital pianos. Over 75% of piano players prefer an acoustic sound, yet most play digital because of price, size, and weight. We want to combine the best of both worlds. We can offer an acoustic piano that weighs only 40+ 15 kg, only occupying half a square meter of valuable living space. It can be transported in normal cars. The first model has a slightly reduced amount of keys (just like many digital keyboards) having all the keys for pop and jazz but also most of the classical music in the first five years of music schools. We use one string per key which allows us to build a piano significantly lighter, even with long strings to maintain optimal sound quality. We thus have a strong focus on sound quality, rather than loudness. We can reach the low price due to automated production here in Europe and a design strategy that allows this. We started this because we needed it for ourselves and saw the need for others. We asked all the piano enthusiasts we could reach and get the interest in our product confirmed. The huge market of acoustic and digital piano (we combine the benefits) is what keeps us on pace to release a great product.
