A Moment of Bach

O Lamm Gottes, unschuldig (BWV 656)

A textbook "moment" of Bach -- in a charming setting of the three verses of the German song "O Lamb of God, Most Holy," suddenly near the end of the third verse Bach finally heeds the text and shows us the strange despair we are praying for mercy to avoid. He employs several musical devices in this sudden moment: a change in meter, a suggestion of a distant tonality, and a barrage of harsh chromaticism (notes outside of the key).

First we learn the background and the tune "O Lamm Gottes, unschuldig" before showing how Bach introduces this Cantus Firmus (melody) in this organ prelude's beginning and first verse where it is heard on top. The Cantus Firmus moves lower in the second verse, and in the third it is down at the bottom in the organist's pedalboard. Here the text of the last line changes from "have mercy on us" to "grant us peace." Ending strong and firm, Bach gives us peace from that sudden harsh "moment."

Thank you to listener David for the excellent suggestion. 

Air on the G String (Air from Orchestral Suite No. 3, BWV 1068)

One of Bach's most famous works, and one of the greatest melodies of all time -- this comes to us by way of an almost impossibly good performance/recording by the Netherlands Bach Society.  By having the first violin part played by a section rather than a solo, they give Bach's wandering melody more purpose than it has in the famous version for solo violin, "Air on the G String", which is actually a re-arrangement of this original version -- and one which, we assert, does not stack up to the original version's greatness.  That greatness comes not only from getting the first violin part back in its proper higher register and key, but also from the interplay of the inner lines in the second violin and viola parts, as well as the famous walking bass line of the continuo part. 

Ultimately, though, it is that upper melody which enchants us most.  Is there any wonder that it has enchanted generations since Bach -- it seems to reach toward some meaning, something just out of grasp -- and will enchant generations to come? Yes, the melody wanders... but not all who wander are lost.

Huge thanks as always to the Netherlands Bach Society for allowing us to use their audio examples on our podcast.

Lobet den Herrn (BWV 230)

Did Bach write this? Many think not. It's brilliant nonetheless! 

We get into a talk about aspects of this motet which would or would not be hallmarks of Johann Sebastian.

Brandenburg Concerto No. 6: movement 3

This delightful jig closes out our miniseries on Brandenburg 6.  Here we speak about the third movement's jumpy beats. and how these rhythmic anticipations give the whole piece a bouncy energy.  Bach, the expert violist among so many other things, gives the two viola parts the most intricate material, playing off each other and passing along the musical line.  Yet, in the ritornellos, he always doubles them, allowing for a rich, sweet viola tone to dominate in this delightful musical treat.

Brandenburg Concerto No. 6: movement 2

Welcome back to our yearly miniseries on the Brandenburg Concertos of J. S. Bach! This is part two of three. Today we look at the languid and luscious slow movement of Brandenburg Concerto No. 6.

Music is (often) a setup of expectations, and then the satisfying fulfillment of those expectations OR the clever subversion of those expectations. Bach is especially good at this principle. We focus first on the unusual written-out cello part, separate from the basso continuo, creating a new entity but bound to the bass still (heterophony). Then we look at Christian's two moments, both of expectation and then subversion.

Brandenburg Concerto No. 6: movement 1

Welcome to our yearly miniseries on the Brandenburg Concertos of J. S. Bach!  Here we jump into Brandenburg 6, delighting in the weirdness that results when Bach decides to omit violins, preferring a dark, low sound of violas, violas de gamba, cello, and violone.  This brings us to some more examples across Bach's oeuvre, as well as some others by Brahms, Bruce Broughton, and John Williams.  As any creative person knows, setting limitations for yourself -- "no violins", for example -- is actually a good strategy for stimulating creativity, and results in a more unique creative output.  How fortunate for us, then, that Bach seems to agree.

Goldberg Variations: 7 (canary jig) (part 2)

Today we return to the 7th of the Goldberg Variations, the "Canary Jig." We discuss that peculiar name, and then we get into some smaller moments. Soaring flares up the keyboard, surprising altered tones, and crunchy grace notes are all over. Pushing forward into the ending, a high note leads us to the finish. We discuss why the contour of the hands makes this ending so satisfying.

Du Hirte Israel, höre (BWV 104): bass aria

Just after Good Shepherd Sunday, we settle in to this comforting pastorale.  Not the famous opening movement -- no, this is another beautiful sicilienne-type dance, a bass aria, in which Bach gives a masterclass on melodic writing in just 5 seconds of music.  Melodic shape, sequence, pedal point, and effective parallel motion in triads -- these are all showcased in the first few measures.  Then, Alex points out his favorite moment, in the B section of the aria: a long note sung by the bass soloist.

Goldberg Variations: 7 (canary jig) (part 1)

In our second look at the monumental Goldberg Variations, Christian selects the beginning of the sprightly and innocent "gigue" (jig), a particular dance set here for an interplay between two hands. The jaunty rhythm of the dance is rather uneven; this leads us into a discussion about how music is naturally not even in this way (and when it is, it's too square). We discuss the Goldberg bass line which underpins the whole sequence of 30 variations and discover how it works with this one also. 

In two weeks, Christian will return to this variation and get more into the weeds with particular notes.

Chorale: Ich steh an deiner Krippen hier (BWV 469)

Just as the three wise men brought their gifts of gold, frankincense, and myrrh to the young Christ, so also this trio brings their soprano voice, viola da gamba, and theorbo (a lute variant) as musical gifts.... and we, the listeners, are the ones who are lucky enough to receive these gifts.  Here we discover the plain serenity of this original hymn tune by Bach, set to simple accompaniment, and paired with a tender Christmas text by the venerated hymnist Paul Gerhardt.

Performance of "Ich steh an deiner Krippen hier" (BWV 469) by Viola Blache, Mieneke van der Velden, and Mike Fentross for the Netherlands Bach Society

Speaking of gifts -- we must, as always, thank the Netherlands Bach Society and the evergreen gift they provide for the world, the All of Bach project.  They are working to complete a full set of high-quality recordings of Bach's complete oeuvre, along with video for each piece.  This is a staggering amount of music.  These are the recordings we have used on this podcast since its inception.  Thanks again to the Netherlands Bach Society for granting permission to use these excellent recordings.
