Ui Young Kim is a renowned concert pianist who established a company in 2013 with the primary objective of providing a convenient and cost-effective music learning option for people interested in the classical music genre. The company's flagship product is Pockestra, which is an Artificial Intelligence (AI)-based instrumental accompaniment mobile application that enables users to access and practice classical music accompaniment on-the-go from anywhere in the world. Pockestra provides high-quality accompaniment tracks by using advanced AI technology to simulate the sound of a real orchestra. The mobile app has an extensive library of classical music pieces, including popular works by famous composers such as Mozart, Bach, and Beethoven. The app allows users to select the tempo, pitch, and volume of the accompaniment tracks to suit their preferences and needs. The aim of Pockestra is to promote music education and to make classical music accessible to everyone, regardless of their location or financial status. The app is targeted at music students, professionals, and anyone interested in learning classical music. It provides an alternative to the traditional method of learning classical music, which involves hiring a professional accompanist or joining an orchestra, both of which can be expensive and time-consuming. Overall, Ui Young Kim's company is dedicated to democratizing classical music by providing a technology-driven platform that simplifies the process of learning and practicing classical music. Pockestra is an example of how AI technology can be used to enhance the music learning experience, making it more accessible and enjoyable for a wider audience.
