India Musical Instruments

We have become familiar with a number of classical Indian musical instruments. We have not seen a large number of different instrument, but we have seen that there are large variations among the basic ones we have seen. We have purchased several- including Tabla (small sort of drum), Sarode. Veena and Tambora (these are string instruments which are plucked) as well as a larger decorative drum and a number of small instruments which would be considered percussion instruments. We have no idea how to play these, but they look rather nice and make interesting sounds. We also have no idea how they are to be tuned, so we probably won't be masters of them any time soon.
There are many music shops around Bangalore. they mostly sell modern western instruments. Guitar is very popular as are electronic keyboards, but you can still find the classical instruments too. The classical ones are all hand made and each is unique. Many of them look very similar in size and color, but then sound quite different. The ones we have, mainly look nice, since we can not judge the sound well, but some dealers will play them and let you hear the difference and generally we agree when they say one is higher quality than another- based on the sound.
We visited one shop which has about 3/4 western instruments and 1/4 classical India ones. and found a technician working on a Veena outside. This is almost certainly a new Veena and he appears to be completing it. We think the basic instruments are made elsewhere and then shipped to other cities. This fellow apparently repairs the instruments as well. The Veena we bought, looks nice, but needs some repairs and strings added as well, so we hope this fellow will fix it up for us.
