For the past 2 decades, Yamaha have been providing affordable high quality keyboards, having good tonal quality, and many rhythms required to play songs. Yamaha PSR E series was dominating until PSR I series were introduced. PSR I425 was first introduced, then I455, and now PSR I500. These keyboards have beautiful tabla rhythms, mridangam tones and tampura, which helps keyboard students to practice the songs with a good rhythm. It is also useful for them to practice the vocal music along with these rhythms.

There are some Casio keyboard available at lower costs, but the tonal quality of PSR I500 and the tabla rhythms quality are uncomparable.
