“Droning” has become quite popular, but I only “drone“ to try to remind myself how badly out of tune equal temperament thirds, sixths, and sevenths sound - and just how they DO sound… (I don’t believe I need any practice with so-called mathematical “no-beats” intervals) … so I use one cheap tuner to supply the drone pitches, and another cheap tuner (which is set up to only hear my tuba) to show me when I’m dead on in tune, as far as equal temperament is concerned… It’s not pretty.
As I’ve stated quite a few times… Back in my guitar days, I started out as a little kid with a pitch pipe, then moved on to a tuning fork and harmonics, and then finally was able to hear an E without using a tuning fork, and tuned with harmonics and then went back and de-tuned the guitar so that it would sound equally good/bad in D-flat major as in A-major (because I wasn’t a rock ‘n’ roll player, but a jazz, standards, and bossa nova player - who played songs in all sorts of keys).
Probably half the time - as a tuba person - I work with keyboards, and half the time I work with symphony orchestras, so I’m dealing with both (a type of) equal temperament, and a type of perfect intervals tuning. When there is a piano concerto, I try as best I can to be conscientious about tuning with the left hand of the solo piano (ie. flat) - though (depending on the quality of the orchestra) sometimes, I am forced to go with the tidal wave of the ensemble tuning.
one last thing:
I used the huge B-flat on most of the tunes today – euphonium on one Gabrielli piece. i’ve spent quite a few hours with that instrument, but every once in a while my slide micro-tuning strategies get mixed up still to this day (as it is still new to me, I’m not quite automatic yet). I missed a few micro-tuning slide positions during the rehearsal, and (of course) I heard the not-sparkling tuning results, but observed this: An out-of-tune tuba doesn’t ruin things as much as an out-of-tune higher-pitched instrument. Rather than really ruining things, (simply - as long as the tuning flaw is not absolutely horrible) the sparkle is gone from the chords.
I guess that’s enough for now. I’ve probably bored everyone just about as much as I usually do with this sort of post.
