Anybody else feel the same way about the bowed strings?

I think the Cello is my favorite out of the bowed string family. Yes, I like the brightness of the violin, but it can easily go from bright to SCREECH, especially in the high register. That's not to say that I avoid the third octave completely, I just treat the third octave as the "Solo Octave" and have the other instruments back off in complexity when the violin gets that high. Then when it goes back down, I have more equality once again.

The viola is such an underappreciated alto instrument that it even gets prejudiced as a "violin fail instrument" or "only used for arpeggios and other figurations" when neither of these is actually true. I try to show that the viola is not only for figuration purposes in my pieces by having places where the Viola takes the primary melody or a countermelody or in the case of an orchestral work where I want to build a textural creschendo as well as dynamic(like my most recent, March of Iwo Jima), have the violas play before the violins take the same motives higher. That is melodic and harmonic purpose all in one(because usually the Cellos and Double Basses will be in octaves for most of it, so the violas make it actually sound like a chord progression is occuring).

Now to my favorite, the cello. There is so much variation in cello timbre across it's range(C2-G5 generally) From C2-G2, it sounds similar to a Double Bass in depth. From G2-G4, this is generally where most of my cello writing is at, the soulful range(especially so in the case of a cello solo). G4 and up is what I consider to be the Violin-like range and generally speaking, if the melody goes up that high, I'll have the violin take it from there, but have the cello harmonize it so it doesn't feel like anything has been lost by changing melodic instruments. I myself hope to play the cello someday, but right now, I just can't afford it, not even a beginner quality one.

The Double bass, it's similar in that it has multiple timbres across a wide range, but it's high range is more high viola like than violin-like in that it isn't as bright. It's soulful range has more depth than the cello's(and is also less extensive than the cello's) and it's bass range is more extensive than the cello's also.

Of course, for all of these instruments, register is not the only factor into the timbre, but it is a reasonable starting point.

Examples showing the ranges and timbres of each(and in the case of the viola, hopefully showing that it's equal to the others:

Double bass in all registers:

Violin in it's safest register(least likely to both get swallowed by lower notes and screech):

The viola is wonderful,
