well, copyright in the composition is supposed to expire 50 or 70 years after the death of the last co-composer (different rules in different countries, again). It is not supposed to be paid for live recordings, since it has been paid already for the live performance that has been recorded.It isn't that simple as there is a copyright in the recording and a copyright in the composition.
The term "fair use" is used a lot by folks that need an excuse to steal. Performing for your friends is not the same as making illegal copies and posting them online.I thought there is a "fair use" clause pertaining to music, sheet music, etc. So long as someone is not trying to pass off copyrighted material as their own original material, there shouldn't be a problem. Anyone who has ever played a cover tune in a band is in violation of copyright. If you've played a CD for a bunch of friends, you're in violation according to some people's legal interpretations. Or how ridiculous is it to refer to Autumn Leaves as "Fall Foliage" or some such silliness for fear of copyright yadda yadda... Everyone knows you're referring to Autumn Leaves, and everyone knows the melody, the chords, etc. Why the obfuscation?
Yes, if the tune is in copyright, of course that would be illegal. But you'd probably "get away with it" unless you had a very famous and popular blog.Is my transcription and/or it's copy an illegal piece of sheet music? I privately used it to help my buddy figure out his now favorite tune. If I scan my transcription and post it on my blog, am I in violation?
No, but they can make quite a contribution towards them not happening, or if they do happen then they can be less serious e.g. seatbelts, crash helmets, air bags. Compulsory insurance may also contribute a lot to people's safety in many circumstances.Motor vehicle laws can't stop accidents from happening.
See above. I think you probably have a different definition of "illegal" to those who make the laws.And BTW, don't take this post as condoning illegal usage.
