If you are a music enthusiast and have a passion for instruments, you definitely will find your own way to learn the keys whatever kind of piano you have, whether a portable or a grand one. When you already knew how to press and master a phrase of a song, you tend to ask for a higher version to encourage you more to learn like a professional player. There are many brands of pianos in the market but the first thing that most people consider is the one with gorgeous keyboards. True enough because it makes one learning more easier and enjoyable.
If you have kids and you want them to play a piano, involve them in choosing what they think is easier for them to learn. Consider the brand but this is not really important especially for beginners. It should be with standard touch to fit for the children. Check the websites for the price and other reviews to help you decide. There are sizes to consider too but it all depends on who will use the piano. If it's for family use, a grand baby piano is a better option if you intend it only for your house, of course unless you want to do a concert, then consider the largest grand. Another thing to consider that matters a lot is sophistication and should also compliment the decorations and other set of furniture in the house.
