Whether or not you decide to take piano lessons, if you want to make progress at the piano you will need to spend some time at the instrument!
These days there are many options when it comes to pianos. You can get an acoustic piano (grand or upright; both come in various sizes), a high-quality digital piano, a digital keyboard, or you could even use a MIDI controller connected to a computer.
You can rent a piano, you can buy a piano…the choice is yours.
Acoustic pianos come in a great variety when it comes to brands, not to mention sizes. The major advantage of an acoustic piano is that, when playing, you are producing a real sound!
With time, you can learn to control the sound you produce. You can produce shades of sound, playing more expressively and shaping the music you are playing. Of course, in our opinion, sound and action quality matter deeply when it comes to choosing an acoustic piano, and an acoustic piano that doesn’t sound very good is not a good choice, even if it is in good condition and ‘works perfectly’.
Buying a piano, or renting it, is not the only option. These days there are very good options for keyboards, if you don’t want to go the acoustic route. Some of these keyboards have a great sound, and you can attach a plug-in pedal that looks and functions much (though not entirely) like the real thing.
