Composed by: Mariza Costa-Cabral, except for the part from 1:45-3:51 which is Bach's BWV 999, with its rhythm altered by Mariza.
Arranged, performed and engineered by: Ed Hartman (edhartmanmusic.com). 

There was of course that summer night when Johann Sebastian Bach lied down on his back, looked up at the sky, and let his mind bring him back to his early childhood in Eisenach when his parents were still alive and he lived with them and all of his siblings, and he felt whole again for a few minutes. (Johann lost his parents at the age of 9.) That night, his little prelude BWV 999 might have played in his mind and, although it did not sound like this, it may have felt something like this.

By the way, I liked the following interpretation of BWV 999: https://soundcloud.com/bibliotecaperezcruz/j-s-bach-preludium-in-c-minor-bwv999

Träume von Eisenach - by Mariza, arranged by Ed Hartman

I am a scientist who started composing music as a hobby in 2013. I have not studied composition and do not approach it analytically, only intuitively. I took piano lessons in my childhood and teens, but spent most of my adult life without playing piano until 2013. So far I have composed mostly for piano, in a polyphonic style that borrows from the Baroque as well as the Romantic spirit. I describe my style as "Baroquemantic". 

Most of my piano pieces are easy to play.  Some are very easy to play.  

All of my pieces rely on 2 or more concurrent melodies (counterpoint).

A Portuguese guy called "Carlos Miguel" wrote the following on YouTube and  I think this is so so so so true! I will be quoting him everywhere I can:
"...a boa música é como as boas palavras, depende de quem as diz e de quem as ouve...podem não vir a ser nada e podem ser tudo...ou ambas as situações em simultâneo...genial também é quem ouve...pelo seu modo de ouvir... e não só quem  compõe...pelo seu modo de compor...Carlos Miguel"

Freely translated from Carlos Miguel: "...Good music is like good words... it depends on who utters and who listens... it can be nothing or it can be everything... or both simultaneously... for there to be a work of genius there needs to be a genius listener as well as a genius composer..."
