I hope this it the right Forum. It involves the Technique to play a fingered Extension in this Piece.... If any of you have played this, you know what i am referring to. My part is 12 pages...on pg.2, of the Allegro Con Brio, Bar #168 (reh.B) is the first Low C. This is playable....... Bar 186, Low D.. looks dooable depending on the tempo.. 479-to 485 I have to play Es, Fs D and C.. Will I scrape my Knuckles on my 'G' String tuner as I finger the E,F and D moving around? Does this happen? It's been 30 years since I have a Bass with a Fingered Extension and can't remember. The 32nds in the Andante, towards the end of it has a low D within a fast moving part. Is this doable at all with any kind of extension or does it call for a 5er or play it up... The piece looks mostly doable with an Extension but we don't rehearse this for months and I don't know all the tempos yet. Who has played this with either a Fingered Extension, Mechanical Ext, Fiver or multi latched (sliding or chromatic) Ext., 4 str up an octave, 4 tuned down??
