Hello David, Jason Thank you for your responses. David, I am a PTG associate and I do tune aurally and I have been studying the PACE books and the exam source books as I would like to in the near future take the PTG exams. My battle is I have no one to mentor me. I have to read and apply what I read and work things out by trial and error, but I am learning and enjoy being a tuner/technician. I asked the question about the double octave stretch mainly because I thought that there is an unspoken amount of stretch that tuners use in concert tunings in big halls and I just wanted to find out if is so? I am reading at the moment about, and beginning to practice, the 6:3, 8:4, 10:5, 12:6 single octaves for the bass, 2:1, 4:2 single octaves for the middle range and then the 4:1 double octave for the middle and treble and the 8:2 double octaves for the bass. What I really enjoy about tuning the bass is ghost tuning. It is very helpful. I need to work on my treble and high treble tuning to get good consistent progressing 17ths etc. And yes, unisons and stability are essential to tuning!!! Jason, a very interesting find! Thank you for your input too! Thank you once again for your responses. Take care, Mark -------------- next part -------------- An HTML attachment was scrubbed...
