How To Tongue The Note B flat in the Second Octave When we introduced A in the second octave of the bass you will have noticed that it had the same fingering as for low A but with the thumbhole slightly open. There are quite a lot of notes in the two octaves that have this similarity. Unlike most smaller recorder, some basses allow you to leave holes 7a and 7b open for the low B flat which makes moving between the two notes an octave apart much easier. If your bass is sharp on the lower B flat when holes 7a and 7b are open then you must revert to the standard fingering for low B flat with these two holes closed. If you play successively the middle and bottom B flat you should soon find the finger movements you must make become instinctive, as well as deciding whether you need holes 7a and 7b closed to produce a good octave between the B flats. In every other way, middle B flat like middle A before it is an easy note to play and you should be ready to play piece no. 18 to familiarize yourself with this new note.
