Tutorial on how to play piano/keyboard playing with just the black keys.
The magic about this is that like this ya 've already set ya 'harmonic home base' and so you can't hit any 'wrong sounding' keys.

That's a good ground to freely improvise and get into some flow experience.
Guide lines:
0. Left hands does the bass half of the keys / right's on the higher notes
1. Left hands starts ( and ends) at 2.nd of the two black keys. 
( This key is named E-flat [Eb] ) With ya hand span one octave. 
In the bass  keep that wide range. Avoid hitting neighbour keys here at once - nice that'll result in just a dull sound.   
2. Right hand just plays on black keys. You may hit more than one key at once :) 
In contrast to the bass here also narrow range keys sounds well.
3. From the white keys you may add the F and B. 

So technically ya play Eb-minor pentatonic scale. That's a five-tone-scale.
Playing the same on the white keys(starting at A) you'll get an A-minor heptatonic scale. What will be a seven-tone-scale.
However sometimes less is more - so for the beginners or music-harmonic-explorers a pentatonic is in my eyes the best to start with. 5 like the 5 fingers on the hand. The Orff-approach: https://en.wikipedia.org/wiki/Pentatonic_scale#Role_in_education
