There are options that abound for those that want to learn and practice piano. People that have been throwing around the idea of how to play the piano can go online and utilize a real life piano on their screen and start learning the tonality and sounds simply by pressing buttons.
People that aren't aware of the keys, nor want to invest a great deal of money into getting a physical keyboard or piano can get their feet wet in terms of sound. Learning how to play the piano has a lot to do with sound and listening to the vibrations of tones that come through the ear. WIthout knowing what the notes sound like on an individual manner, a person can not learn.
Yes, there are some that will find learning the traditional way to be easier, but with modern technology, traditional learning experiences aren't always the best or easiest.
