Q: done the f notes- https://imgur.com/a/W96VD
another question: f sharp and g flat are the same on the piano right? is there a reason you'd pick one over the other when writing?
A: yes they are the same. there are various reasons you might choose one over the other. when we get into key signatures you should see this a little more clearly. if you have d, e, f#, g, a, you always want to use f# there instead of Gb because that way you have one letter for each note (one note on each line or space). if you used Gb in that situation, you would have no Fs and 2 Gs and you would have to keep flatting and unflatting the G. the 5 notes i just mentioned are actually part of a D major scale. so when you are in D major, for example, you can actually put the sharp symbol on the F line, at the beginning of the chart, (and also on C#, for the key of D) and then you can just use all the notes normally from D to D, and it automatically makes a D major scale because you already specified that the F and C notes are always sharp. (that is called a key signature). if you tried to use Gb and Db to make a D major scale, you would have to constantly be flatting and naturaling the D and G. it would be a freakin mess. but with a key signature, you just flip the F and C to sharps at the very beginning, and then all the notes in your staff automatically make D major. then if you want to flip to D min for a moment, you can use a natural sign on the F to make it temporarily natural. let me know if this makes sense and then i can try to show you the key signatures in a logical order
