(back) Subject: An Interesting Experience From: "willh" <willh@cfl.rr.com> Date: Mon, 26 Jun 2000 08:57:43 -0400     Dear List,   I attended the installation service for the new pastor of the church that I was formerly organist at yesterday. It was quite an experience, not the service it self but all of the comments I heard about the music since I've been gone. "We miss you, Will!", " That organ hasn't been the same since you left.", and "I don't think you'll enjoy the = music." were just a few of the comment I heard yesterday. Sadly, most of it was true. The organ at this church, (an Allen MDS-26) while nothing too = special sounds very good in the church. I was quite flattered by what I heard. It seemed to me that they miss what they had in me, and that they are starved to hear good music from the organ.   The woman who replaced me is not an organist at all. She = is a piano professor at our local community college, and does have a good keyboard background, but no organ experience. Another sad thing is that = she is not willing to accept suggestions or criticism about how she could improve her music. She knows nothing about registration and the only sound we heard from the organ at this service was Diapasons with Mixtures. I was told that it has been this way for a year, and that the congregation has heard nothing from the organ but Diapasons with Mixtures!! No Flutes, Strings or Reeds!! Just Diapasons with Mixtures!! For Preludes, Offertories, Hymns, and Postludes! She doesn't even use the pistons, she leaves the same stops on all the time. I think they have lost some of = their musically educated members because of this.This is a real shock for them because I used every stop on that organ and switch registrations = constantly.   They seemed to look forward to her month long vacation = with great anticipation, and were even more excited when I told them that I was going to play for two Sundays. I didn't really know what to say back to them. So I tried to tell them that this was a good experience for her and that maybe she'd learn about the stops when she feels more comfortable = about the organ. She has started to play the pedals a little. I also reminded = them of me and my first few weeks there. Back then I was as green as a leaf, = but over the next three and a half years I improved greatly.   I don't know if anyone is really interested in this but, = it was such an experience for me that I had to share it with you.   Sincerely,   Will Scarboro

They are very knowledgeable about registration and use a lot of variety in the hymn playing. The congregation really likes the new sound.   Later, Phil L.

(back) Subject: Dennis James- Seattle Paramount - July Silent Film Series starts next Monday From: <MUSCUR@aol.com> Date: Mon, 26 Jun 2000 14:18:40 EDT   It's that time again- Summer Silents in Seattle.   This year we open the award winning "Best of Seattle" silent film series = this next Monday, July 3, and run for consecutive Mondays. The July 2000 = series is a dual tribute to archive film preservation and the work of D. W. Griffith, the "Father of American Film," with screenings of the Museum of Modern Art's meticulous restorations.   The D. W. Griffith silent films ORPHANS OF THE STORM (July 3), WAY DOWN = EAST (July 10) and the epic INTOLERANCE (July 17) will be shown with beautiful = 35 mm color-tinted prints and at the original projection speeds. I'll be playing my transcriptions of the orchestral scores written for each film's =   initial release on the theatre's restored 4 manual 21 rank Publix No. 1 WurliTzer unit organ. Louis F. Gottschalk (nephew of the famed Civil War = era touring pianist/composer) compiled the ORPHANS OF THE STORM score in 1921- = a busy year for the Hollywood film composer during which he also scored THE THREE MUSKETEERS for Douglas Fairbanks and Rudolph Valentino's debut in = FOUR HORSEMEN OF THE APOCALYPSE. William F. Peters, a beloved composer of = piano characteristics, accepted Griffith's commission to score the rural = melodrama WAY DOWN EAST in 1918. Griffith chose Joseph Carl Breil (1870-1926) to followup his superb 1914 score for BIRTH OF A NATION with the 1916 = sequel, INTOLERANCE. Breil, known mainly for his opera works, was the first = American composer to create a score specifically for a motion picture: QUEEN = ELIZABETH of 1912.   ORPHANS OF THE STORM was D. W. Griffith's last blockbuster epic, and the final collaboration between the great film director and his discoveries Lillian and Dorothy Gish. It tells the story of two orphan sisters' = struggle to find each other with the French Revolution as the dramatic backdrop for =   their journey filled with suspense, humility, and love. A classic in its = own time, WAY DOWN EAST is one of D.W. Griffith's finest rural melodramas in which Lillian Gish stars as a young country girl on a journey through = tragic circumstances. INTOLERANCE and its terrible effects are examined in four historical eras: ancient Babylon, Christ's Judea, 1572 Paris, and early modern America,1920's style.   Each program has a start time of 7:30 p.m. with my pre-show lectures with = Q&A at 7:00 p.m. The theatre is located in downtown Seattle at 911 Pine St. = and the web site is at www.theparamount.com Tickets for Silent Movie Mondays = are on sale now, and are available at all Ticketmaster outlets, charge by = phone at (206) 292-ARTS, or visit The Paramount Theatre Box Office.

The usual practice for a "sub" that wound up on a Hammond was to use the gawdawful factory presets, and then blame the organ. The drawbars, in the hands of someone skilled in the art, could make some very listenable tonalities. I found the Hammond Organ over the yeras to be an excellent teacher in the field of harmonic composition and tonality. I = can listen to a pipe and tell fairly accuaratly which harmonics are present = and what their relative strength is. Most organists cannot do that. I credit many hours of goofing with various Hammonds at developing this skill.   DeserTBoB

Shielding isn't even really necessary, however, if one = simply runs a +4 VU 600 (or even 150) ohm balanced line from the organ to the powered speaker. Costs a bit more, but the benefits are many. 22 guage twisted pair works well for these applications (as if has in the telephone industry for 100 years), and shielding definately won't hurt, although = it's definately not necessary in this instance. All induced RF and noise is simply cancelled out to ground at the receive transformer (or balanced input amp, which is more the norm now).   DeserTBoB

The organ is a WIND = instrument. <snip>   I would kind of agree with Alan on this one- when you mix and match different parts you never know what will result. I can see how Rodgers does the pipe/electronics, but they have engineers that can figure it out. Just buying generic 'electronic ranks' and sticking them in with 'the real thing' could come out sounding very good or be a total disaster. You would know that pipes would sound good and blend in. They may be more expensive, but in my opinion it would be worth it.   Paul

Thank you for you well wishes. We are having the ceremony and reception at the John Leckie   Music Centre. The home of the Western Australian Theatre Organ Society's   Compton 3/10 Theatre Organ. The ceremony will be followed with a lunch with family and friends then at 2:00 pm we normally have the members' afternoon to which we have invited additional friends and family to join   the members. We will be cutting the cake during the members' afternoon and putting on a special afternoon tea. The afternoon will end about 4:30 pm. It should be a great day. We will then be driving into the lovely south west of Western Australia to stay for a couple of weeks in a small country town called Nannup on a private farm with deer, cows and sheep roaming around. The cottage will overlook a stream under 100 year old Tuart trees. We are really looking forward to the break. We will be returning to put the program to air the following week and then heading back down south again.   Cheers, Dave McPeak <Mack>

I do hope that you are planning on having this done by your service person/technician/organbuilder. And most of them have their preferences as to the type of solid-state equipment they use. It seems that the two most popular types among organbuilders are the Peterson and the SSL relays. Both of these companies have quite a good track record for installations.   As far as digital voices, if you ABSOLUTELY have to add them, I would look into the Walker digital voices which can be gotten by your builder. They are heads above any of the other digital voices on the market. And especially if the builder is familiar with the Walker system, they can really be voiced to fit the organ and the room.   Best wishes with your project.   David
