Ninth chord
A revision of the analysis of the cross relation of April 22, 2008
Here is the original post with sound files of the parts.
A dominant seventh chord is built of four scale degrees: the fifth as the root, the seventh scale degree as the third of the chord, the second scale degree as the fifth of the chord and the fourth scale degree as the seventh of the chord. The fourth scale degree resolves to the third scale degree, thus acting as a passing tone.
Listen to the progression: i V V7 i:
Here is a discussion of chords and seventh chords.
The dominant ninth chord adds the sixth scale degree as the ninth of the chord. In four part writing, one note must be omitted, usually the fifth of the chord, the second scale degree.
Pertaining to the omission of the root of chords, R.O. Morris says: "It seems to the author…that a chord from which the root has to be omitted ceases ipso facto to be that chord at all, and that no suport should be given to so paradoxical a method of classification."
So I have revised my speculation about the analysis of the phrase in BWV 114.7 with the cross relation; I have changed it to the analysis shown below. I think this unnecessarily complex, cumbersome and academic analysis highlights the fact that Bach wrote chiefly with melody in mind and was not concerned with the mental anguish of his students three hundred years later.

Trinity Sunday 2008
Cantatas for Trinity Sunday
For Trinity Sunday, Bach wrote three cantatas. He also revived BWV 194 on Trinity Sunday, June 4, 1724; it had originally been written for an organ consecration on November 2, 1723.
Take your pick.

Whit Sunday 2008
Pentecost, the fiftieth day after Easter with J.S. Bach and Alexander Sadoyan..
Painting by Alexander Sadoyan.
For today, Pentecost or Whit Sunday, we have BWV 172, "Erschallet, ihr Lieder, erklinget, ihr Saiten!" ("Ring out, you songs, resound, you strings!"), a favorite of mine, which concludes with a four part chorale with a wonderful violin obligato. It was written for Pentecost Sunday in May 1714, so is one of Bach's early cantatas. He also played it several times in Leipzig with some alterations.
Alfred Dürr says of this cantata: "All the various changes he made show how much trouble Bach took over a work which—as the number of documented performances (at least four) suggests—he seems to have particularly loved."
I have several performances of this cantata: Leusink, Leonhardt, Koopman, Suzuki, Rifkin, Gardiner and Rilling. The large number of performances available is another indication of the popularity and appeal of this cantata. The opening chorus is very festive; it puts me in mind of the opening movement of the Christmas Oratorio.
The six parts of the cantata are:
opening chorus
bass recitative with a low C at the end
bass aria
tenor aria
alto-soprano aria with the chorale "Komm, Heiliger Geist, Herre Gott" in the instruments
closing chorale with violin obligato.
As for the low C discussed at such great length on the Bach Cantatas Website, it is most audible on the Suzuki performance, but all the basses do well. The most joyous performance for me is Rifkin's. His choice of one voice and one instrument per part also allows the violin obligato to shine through on the final chorale.

A Cross Quarter Day
A cold day in Los Osos.

Two egrets stand in the chilly wind with necks contracted to keep warm. It doesn't really seem like Spring, much less the beginning of Summer in the old calendar. It feels like a California winter day and I am barely comfortable wearing a jacket with a wool lining.
Moro Rock is in the overcast distance.
However, cold as it is, I am having a very nice visit with my daughter and granddaughter.

The Ascension
The Feast of the Ascension with Medieval Wall Painting in English Parish Churches and Bach's Cantata BWV 37, Wer da gläubet und getauft wird.
I was captivated by this wonderful photo by T. Marshall of a wall painting in Seething, Norfolk. I love the feet disappearing into the void, perhaps a cloud, or perhaps there was a full figure originally and it has been obliterated. I love the warmth and color and the suggestion of the upwards watching friends and family below. Very likely this painting was detailed when created originally, but I believe its charm has grown with the passing of centuries.
I have just begun listening to cantata BWV 37, and am growing to love it. This cantata dedicated to faith is not grand, but is written on a small scale. There is a gentle energy in all parts of the music. There is no sense of triumphant gladness, but rather a quiet confidence in the friend who is going before. I especially appreciate the third movement which is a duet by Soprano and Alto on the chorale melody "Wie schön leuchtet der Morgenstern", which appears again soon on Whit (Pentecost) Sunday. I am also very fond of the oboe obligato in the bass aria; much of the energy and forward movement comes from this reed instrument used so often by Bach.
Part two is a tenor aria which originally had a violin obligato accompaniment which has been lost. I favor the violin parts in the Harnoncourt and the Gardiner edition, both possibly written by Alfred Dürr at different times. I do not have the score for any of the violin parts which show up in the excerpts below and the liner notes do not address this issue (a shame). In his book The Cantatas of J.S. Bach, Mr. Dürr says: "…with the aid of thematic material developed in the tenor and continuo parts, it may be reconstructed well enough for no breach of style to be apparent and without the overall impression suffering from its failings." I feel the violin parts as presented in these recordings live up to this expectation.

Cross relation
A 'true' cross relation in measure 3 in a chorale from BWV 114.
Note: Revision and correction to the analysis below, posted May 26, 2008.
In BWV 114.7, measure 3 and measure 7, beat 1 to 2 in the tenor and bass have an E flat in the tenor and an E natural in the bass. The NBA edition and the Barenreiter edition of the chorales show a courtesy accidental on the E flat which does not appear in Kalmus or the Budapest edition. I surmise this is to reinforce the unexpected notation of this true cross relation.
So, why might Bach have done this? The phrase is in g minor; the bass starts on the tonic, leaps up to the dominant, climbs by the ascending minor scale to the tonic, then descends by the descending minor scale to the fourth, steps up to the dominant, then falls back down to the tonic where it started. The tenor starts on the tonic, steps down to the leading tone (the raised seventh of the scale), leaps up to the lowered sixth degree of the g minor scale, then steps downward to the tonic, then down to the leading tone, and back up to the tonic. Two very elegant melodic lines.
Listen to the bass line
Listen to the tenor line
When these two melodic lines are played against one another a harmonic progression results, which I speculate might be read as shown in the above analysis.
