Harmonium

Harmonium will enable you to play different styles of harmonium, perfectly in tune. If you're interested to play indian music (karnatac or hindusthani), this is the perfect "travel" harmonium you need. Tune your harmonium such as the great singer masters where doing, in the indian harmonic scale. You select harmonic scale, and the base note. That's it. If you prefer to play western music, religious music, then tune the harmonium to the common tempered scale. You'll have a big church harmonium
