Accidentals (Sharps and flats) last the entire measure on the line or space they are on (not the note name). So notes on other clefs and octaves are not affected.Then again, you can usually tell by playing the piece (usually......) which one makes sense.
'So notes on other clefs and octaves are not affected.'I thought notes on the other octaves were affected. It's just that some publishers wish to reinforce the point by putting extra sharps on the other octaves. I'm quite sure this applies to notes in other clefs, but I'll ask someone else about it. =)
Yes, and it is in fact called a "courtesy" natural (or sharp or flat as the case may be).Whether or not it is used is a stylistic choice made by the engraver, and some engravers place parenthesis around the mark while others do not.It's my view that music should be engraved as unambiguously as possible with the use of extra symbols where necessary to remove any doubt. So where there is, say, a Bb in one octave, clef, or staff and then a B or Bb appears in another it should be clearly notated as either flat or natural.
Im not disputing you at all,JLH, but isn't there something like a "courtesy" natural that is sometimes used by some publishers to indicate that the sharpening/flattening of the note in the previous measure no longer applies? (Improper terminolgy but I couldn't tresist.)I'd swear recently someone used that term right here on Piano Street and in the context we're addressing.
You're right, many publishers do remove any doubt of an accidental's status by putting a courtesy natural or whatever. However, many times (especially in urtext editions) they aren't there, so you can't always count on them.
Thank you, JLH. Now, if I may, ask...What are urtext editions? I keep running into that expression and never in a context that is self explanatory. The word "urtext" isn't very pretty, in fact I know some ugly, salacious words that are cuter than urtext. But of course, it has a very nice meaning, and I'm simply ignorant. Could you enlighten me, please? Never mind, JLH. I found the definition at...https://en.wikipedia.org/wiki/Urtext_edition...and feel pretty stupid for not having looked before. Poor thing, it's still grotesque. I'll bet all the other musical expressions make fun of it.
