Answer:
1

et me start first: Franz liszt - Liebestraum (or maybe bach goldberg varations.
2:Without intending to offend anyone, I do not see the point in having a secular funeral with secular music. Also, one must point out the obvious, that one is not going to be there to appreciate the event.
Nevertheless, I was a church organist for many years, and if I had been at an important church where I was owed a great funeral, I would have a Renaissance requiem, Victoria preferably, along with his incomparable motet Versa est in luctum, which may be translated as follows:
My harp is turned to mourning, and my organ into the voice of those who weep. Help me, O God, my God, for little are my days.
3:Not a classical piece. I've told my family I want them to play a recording of Billie Holliday singing Please don't talk about me when I'm gone.
4

he fact that one is not there to "appreciate the event" has no bearing on the premise of the thread - an interesting one at that, for even Papa Haydn designated music for his funeral.
I would choose the last 5 minutes or so - from where the hushed chorus enters - of Mahler's Second Symphony.
5:No one these days (at least amongst my kith and kin) is going to appreciate a full Requiem Mass, even Fricsay conducting Verdi, and to be honest it would seem a little contrived, if not overblown, to my taste and in my memory. But if my brother is still above ground, the funeral march from Chopin's piano sonata would be a must for personal, childish reasons
6:Before I quit playing the piano some forty years ago, I decided to leave an LP of some things I liked. Included was the Schubert A Major Sonata, D. 664, and I thought the second movement came out quite well.
Since two friends - the pianist Andrew Wilde and CMG's own Lance Hill - transferred the LP to a CD (Andrew) and made it into a beautifully produced CD jewel case (Lance) -two favors I can't forget - I feel I can't do better than sign off with two pages of Schubert.
But not yet.
7:I'd pick the Adagio of Spartacus and Phrygia and/or Lament of Phrygia & Requiem from Khachaturian's ballet Spartacus.
8:Berlioz' Witches' Sabbath mvt from Symphonie fantastique performed by the Philadelphia Orchestra & conducted by Leonard Bernstein.
9:I mentioned both times a selection of Rachmaninov's Vespers would be nice at my funeral. Not the entire Vespers of course, as I would not wish to take up anyones day. The shorter would be the better the ceremony.
But now that I'm still around, guess i still can change my answer, yes?
Then maybe a selection from one of Schnittke's 2 choral works. Choir Concerto or his Requiem. Which selection not sure as yet. But should make a decision, and will mention to my wife which selection tomorrow.
Man is she going to freak, she is superstitious on things like that. "oh don't talk death, are you crazy?"...Funny gal.
10:My recording of Abschied (Parting) from Schumann's Waldscenen. Appropriate for the occasion, and I think one of the best things I've done. But I'm not in any rush!
