• Do you think music is amazing?
l think it's great
• Music is awesome! It is a usefull thing! Its very fun!
• Is there an easy way to remember the names of the key signatures?
Thanks
• The easiest way for me to remember the names of the key signatures is to use the circle of fifths. Here is a link to an article that contains this circle and more information about music theory. http://openmusictheory.com/keySignatures.html Also: "fATHER cHARLES gOES dOWN aND eNDS bATTLE (the lowecase letters are the sharps)" is a mnemonic I use to remember the key signatures for sharped keys. The link I sent talks more about this.
• He mentioned that you can't have both flats and sharps in the key signature but can you still place flats throughout the piece if they are marked as so if the key signature is a sharp and vice versa??
• Above answers being true, generally, when choosing or playing a key is best to stick to sharps only and flats only. This ensures that you get all 7 of the notes (either with sharps or flats.) Let me demonstrate: If we chose to play D major (F#,C#) but instead of F# we put G flat we would end up with these notes: D E Gb G(natural) A B C# (D). So we have no F of any kind and 2 types of G. thats just confusing right? So generally, even in atonal music, we tend to stick to either sharps or flats. Of course it is possible to put both (music afterall is free) but only in complex instances.
• At , he says that all Fs become F sharps. Does he mean the Fs in that octave or every F in every octave?
• If the sharp is in the key signature, then ALL the Fs become F-sharps, no matter the octave, as long as the key signature is there. If it's an accidental in the measure, then whatever Fs are in that measure become F-sharps, no matter the octave. The octaves don't matter.
• how do you know where to put the bar line

• Single Bar lines
The top number of the time signature shows how many beats equal a measure. When that many beats past you put the single bar-line.

Double Bar-lines
Put these at he end of a piece of music.

Dotted Bar-Lines
When you want to repeat a staff of music put that at the end of a staff.

Hope this helps!
• How do add a note or sharp to a note though? I know when there is a sharp or flat sign it becames c-sharp for example but how do you make it a c-sharp and not a c?
• You add a # to the right of the note you want to be sharp. If you want it to be flat then you put like a little b symbol, you can google it. That's how it works for accidentals. If the key you're in just has a note that is sharp or flat, you put the symbol on the line that represents that note, before the time signature.

• When he says if you want a b-natural when in the time signature it says all b notes become b-sharps do all other b notes in the measure become b-naturals or just that one note?

• I play the clarinet and can never seem to get sharps and flats down. Do you have any advice.

• Is there an acronym or abbreviation that would assist me in being able to tell the key signature when sight-reading music? Thank you!
