Those entering the world of the clarinet should know a few things or be aware of certain considerations. First, it should be determined whether arms and hands are already "big" enough for a Bb clarinet. That being said, there are also options with clarinets that have child-friendly mechanics. Once this question is resolved, the question of the German or French system arises, with the teacher, as with all other questions, providing guidance and support. The primary focus of an entry-level model should be ease of playing. Especially as a beginner, one appreciates quick success. A clarinet with a superb sound that forces the beginner to struggle, be it due to the mouthpiece, the reed, or too many keys, tends to demotivate. With the clarinet, as with all other instruments, it's essential that the musician feels comfortable right away. Regarding the number of keys in the Boehm system, which doesn't offer too many choices, one can focus on how much they are willing to spend, and that also determines the choice of material, whether plastic or entirely wooden. The entry-level clarinet in the German segment is also a matter of budget. Those willing to spend a bit more can choose a wooden clarinet with 20 or 22 keys and invest in the future. Those who prefer a more budget-friendly option may opt for fewer keys or a non-wooden instrument.
How can you recognize a professional instrument, or what should a musician look for when looking to buy a very good instrument? A soloist's instrument should be made of wood. This is, of course, a requirement all clarinet musicians share. In addition, there are options to "upgrade" the clarinet. Both in the French and German clarinet systems, there are material variations in the key mechanism, additional trill keys, or bell mechanisms.
