hi nino, great job... E# is great enharmonically because of the key signature, so dont worry...
the assignment is exactly what i asked for... congrats
since i dont know the procedure of how you work with your software i want to make it clear for future reasons.
1- always, always, ALWAYS sing the notes you write or play when practicing a exercise or song...
2- be aware of each interval without using tricks like "ok, in the key of G there is an F# so i just need to write the scale of white notes and add an F# and I have my mode done"... because you would only trick yourself and if you dont know every single thing you do, then later on it wont become natural.
3- i dont think you do this but just in case.. ... if i ask you to write something in different keys do not use the "transpose" option on your midi sequencer, hehehe
so, nino, i think you did a great job and you already told me you were going to sing the lessons, everything is great.. i will be posting your new lesson soon.
