In Indian classical music, there are seven fundamental musical notes known as Swaras. They are namely, “Sa”, “Re”, “Ga”, “Ma”, “Pa”, “Dha”, “Ni”. In this paper, a digital piano has been designed using a microcontroller. It comprises of eight keys for the above notes, along with an eighth note, the upper “Sa”. It is a minimalistic and easy to use piano interfaced with an LCD to provide the user with a visual indication of the Swara being played. Its simplicity and ease of operation, along with a low-cost factor makes it an ideal instrument for beginners. The waveforms can be observed on an oscilloscope and varied for better understanding for the learner. This instrument can also be developed further to form a robust system with more notes and waveforms.
