Choosing your first music instrument
In my opinion I think that the Piano and electric keyboard are probably one of the best first music instruments for beginners to start with. You can learn all of the fundamental basics of music theory and scales without it being too confusing. Comprehending the keys on a piano is a lot easier because the Sharp notes are the black keys and the white keys are the natural notes. Pianos are also one of the most versatile instruments on the planet, so anything that you learn on the piano can easily carry over to any other music instrument that you learn how to play; it is why the piano is normally the instrument of choice for most song writers.
Learning how to play the Piano
If you are looking to buy a new instrument pianos are normally a bit more expensive when it comes to their price range, so that is something to consider while you are browsing for your new instrument. Pianos are also a bit bigger than other musical instruments and will take up a lot of space in your living quarters. However, electric keyboards come in all different shapes and sizes and are normally a bit more affordable for beginner musicians.
Because keyboards are designed the same as a piano you can learn all of the notes on one instrument and switch to the other without any problems. As you progress in skill you can always upgrade to a real piano. Keyboards and pianos can be a bit tricky at first when you have to play chords and multiple notes, for some people it makes the instrument a bit more difficult. The good news is that your hands will slowly adjust to the different positions to play all the notes correctly.
The maintenance with a keyboard is probably the cheapest and easiest instrument to maintain; normally a good wipe down with a clean cloth will do the trick. Pianos however need to be tuned by a professional from time to time and that process can get a bit costly and time consuming. The price for piano maintenance will vary from place to place and will range anywhere between $60 through $200. This work will need to be done about every six months to a year to keep your piano sounding at its best.
Buying your first music instrument
If you are looking for the perfect first music instrument to start with, I highly recommend you start with the keyboard to learn the basics of playing music. If you stick with playing the keyboard you can always upgrade to a piano later. If you ever decide to switch instruments you can use all of your piano knowledge to help you pick up and learn how to play any other musical instrument with ease.
