Thanks for the mouthpiece comparison pics, Roady. That's very instructive... I'd be interested in picking up a Meisterclasse now...
How does it affect our sight-reading?
Based on my experience of diminished tuning, you have to learn where each note is on the new tuning (no surprise there) - you still have to be able to pick out every note at will on the instrument you're familiar with. I know I have other tunings that are displaced by some holes from my main tuning, and I'm not as familiar with them. Then again, I didn't spend the time on them yet! Ah come on, can't I have something for free?
I don't know if the tuning really affects sight reading although the fact that these tunings are symmetrical may help. For example, if you see an A major 7th arpeggio then you also know and can play the pattern in C# (I guess for augmented tunings). So, insofar as some of sight recognition is about recognising melodic patterns, it can help with that.
I agree with the guys when they say that these tunings are very good for ear playing. I seem to remember the circular tuning players saying the same thing.
Obviously, it's a huge chore to retune, replace reeds, custom order or whatever.
A point not to be dismissed! You have to wait for someone to retune, or get good at it yourself over time.
Here are some points in solo-tuning's favour:
- Being able to buy solo-tuning chromatic harmonicas in the shop makes it an attractive option.
- Most of the chromatic harmonica playing on record is on solo tuning.
- If you want to play any of the classical music pieces for harmonica, they're all written for solo tuning.
- It's great for playing in keys close to or modes around the parent scale the harmonica is tuned to.
Again, IMO, for music where having an instrument biased on C major (or other major key) is no advantage, these tunings really come into their own. What I mean by that is that if you're playing a lot in keys other than C, you might as well have some of the advantages of the symmetrical tunings (regularity, easy transposition, limited number of patterns to get all keys, ear playing is probably easier due to regularity of the tunings as listed above...)
