    Re: Defining the ranks of an organ...



    [quote user="AllanP"]Almost all stopped flutes become open pipes at the higher pitches, I forgot to mention that. Also, the reeds need to go as close to the top note as possible.[/quote][quote user="m&amp;m's"]Normally, in church organs, the reeds only go to the 49th note, the rest being flue pipes. I don't know why, since a 4' Clarion goes to the 49th note, that the 8' Trumpet doesn't go all the way to the top, but generally speaking, it doesn't. I don't know if the 16' Bassoon has flue pipes for the top octave-I haven't checked inside any organ that had such a stop.[/quote]A 16' reed stop usually has no fluepipes at the top.</P>


    Thereare twovery good reasons for not having an 8'reed stop go all the way to the top -very high pitched reedsgo out of tune more easily and they are extremely difficult to tune. 8' and 4' reeds might have harmonic trebles (double-length resonators); this can help the tone and the tuning. A 4' reedmight break back to 8' pitch in the treble; even so it is besttohave flue pipes at the very top.</P>


    Aseamlesscrossover from reed pipes to flue pipes is possible with properscaling andvoicing. Onething that helps is to doublethe treble of the flue pipes (two pipes per note). These play at the unison and at the octave.</P>

      Thanks for that answer, SB. You are right-those higher pitched reed pipes are a real bear to get and keep on pitch, and of course the pipes on my church organ are not harmonic length.

      My home organ is a Theatre III with an MDS II MIDI Expander.
      I also have an MDC 10 Theatre spinet.
