On the novice side of things, the lineup starts with models like the Allora AAAC-304 A Clarinet, which is affordable on any budget and fairly easy to play. The next step from there brings us to instruments designed for players with some experience, but not yet at the professional level, such as the Amati Model 371 Intermediate A Clarinet. After that, we start to get into pro territory, which, with instruments like the Amati Model 675 Professional A Clarinet, can still be surprisingly easy on the pocketbook. Or, for players wanting the gold standard for this class of instruments, that's a title usually attributed to the Buffet Crampon brand. A few highlights of those would be the Buffet Crampon Tosca A Clarinet and the Buffet Crampon Divine A Professional Clarinet, to name just two examples.
Ultimately, it doesn't really matter what sort of clarinetist you are - the bottom line is that this selection of A clarinets offers something for everyone, so it's no problem to find the ideal fit for your experience level and tastes. Just start by thinking about what you're looking for in a clarinet, and use that info to narrow down your options. Finding the best instrument for you can really be as simple as that, whether you're a fresh-faced beginner or a seasoned orchestra veteran.
