Bars, clefs, and tutors

Just a little review;

Bars are the same as measures, correct?
Lines are, as the name suggests, the row of measures going across?
K clef is called C clef - and where the K meets in the middle is the C?
highest on staff for C clef is... (this is where I'm most fuzzy) Treble?
Mid - Tenor?
Lowest - Alto?

Also my girlfriend has a piano teacher and I sat in on one of her lessons, the teacher made mention that she charges $20 a week for lessons - is this a good deal? Currently I can't afford it as I have no job right now and no one is hiring in my area but that should hopefully change soon and it seems like it wouldn't be too hard to attain that amount....

I once heard that piano lessons can be in the hundreds of dollars per week/month - is this true?
May I ask how much you usually charge in you're area?

I plan to become a composer when I get out of college - would piano teaching be a suitable 2nd job for that? Is there enough income involved to pay, for examples sake, an $1100 mortgage and put food on the table? Or would something like teaching at a school be better? Naturally you do not have to nor should you answer these questions if you do not wish to.

The more I type the more questions I think of, I should stop now before I end up writing you a book lol...

Thank you for your time, now I'm going to check out you're new music theory videos I have a mid-term exam coming up next week for my music theory class, your videos should be considerably beneficial to my grade.

Hello.

I charge 20€ (something like $25 I think) for a lesson and I consider myself as a rather cheap teacher. Some very good professors in superior conservatories ask for 80 - 100€ a lesson, but I wouldn't recommend them for beginners.

I have no idea how you play and how much you know about music, but the first question I'd ask myself about this job is: would I be able to do it? How much money you'll earn doing it depends almost entirely on your talent: if you're a good teacher and get recognized by official conservatories / academies / whatever they are in your area, then you'll be able to charge a lot and also to get the best pupils...

Being a composer is one of the most extremely difficult things you could try to achieve... If you were to go through all the college studies to become a composer, then you'd rather be able to teach theory than piano, except if you practiced piano like hell in the mean time... And also learned how to teach it! (Two different things...)

Bars are the same as Measures.
The bars/measures ARE the lines going across the staff.
What in the world is the K clef? ;p. Is there a hidden key i've not hered of?
Treble Cleff (right hand), Bass Cleff (Right hand).
Andrew has video lessons that explain ALL this buddy, you can find them on this site, or on youtube.

I think that what he means is "the key that has the shape of a K" (rather of a B if you ask me...) which is the C key, as he said. It's never used for piano, but it is for viola, cello, and some voices.

Ahh, I know which one you mean. It dose look like a B, I always thought it was a B. That clef is called Alto, and changes depending on were you write the clef in. For example if you move it up, it becomes Tenor.
Andrew should cover these in his new music theory lessons. Or you could maybe stretch to a good book?

Well there is not that much to say about this key... As pianists we really don't need it, so when we cross it we just have to know that the middle of the key shows where the C is...
The key is practical when it's placed on the first line (lowest line) because it allows to write for a soprano voice without having to write notes outside the 5 regular staff lines!

Aye, I just mentioned it cause he said he wants to be a composer
