Typically, it's hard to sing and play at the same time, initially at least, if the piece become too complex. When improvising/playing by ear, I want to try to create a different sound with each song. Is this possible using only the piano, or is a keyboard necessary to do this? I switch up chords, but what else can I do in terms of style? In other words, how can I enrich my backdrop sound (emulating a professional level) when singing? I haven't played much with any sophisticated keyboard or sound devices. Thanks.
I like to play a chord and then sing the scale or sing the root note and play a scale. Play, same key chords like Amin, Cmaj, and Emin. They all have the note E in common so, monotony sing the E while going through those chords. It's sounds like your voice changes keys, but you are only singing E note. Works with all Arpeggio type progressions
