An Introduction to Freely-Composed Organ Works

In my former treatise, I explained the chief difficulty of the average organist: (s)he is not an organist at all, but rather a confused and irritable pianist. In the second part of this series, I here recommend a number of freely-composed organ works that should be somewhat accessible to beginners. Links to IMSLP are given, whenever possible.

(attr.) J.S. Bach: Little Preludes and Fugues, BWV 553-560
These eight prelude-and-fugue pairings are most organists' introduction to the freely-composed works of Bach, which is a bit odd, because compositionally they don't resemble much else he wrote for the instrument. Nobody is really quite sure whether these were actually intended for the pedal harpsichord, or written by one of Bach's students, or what. The point is, their textures and proportions suggest that... something's up. Questionable provenance notwithstanding, they are useful pieces, and the counterpoint is generally good, even if not obviously Bach's. Difficulty: easy to moderate

Paul Benoit: Elevations
Dom Paul Benoit was not a major composer, but his harmonic language (akin to Debussy or Ravel, at times) is pleasant, and these pieces are quite useful for service playing, particularly during Communion. I use them regularly.
Difficulty: easy

Edward Elgar: Vesper Voluntaries, Op. 14
It is a pity that Elgar wrote only a few organ works, for these voluntaries are both charming and admirably succinct. (As anyone who's heard The Dream of Gerontius knows, Elgar has his longeurs.) They work nicely as a set in recital, though most can also be easily excerpted. They were originally written for harmonium, and thus require little or no pedaling. Difficulty: easy

César Franck: L'Organiste
Franck is one of the giants of French Romantic organ music, but his larger pieces are far beyond the capabilities of the average church organist. Happily, he also wrote this indispensable collection of short pieces for harmonium. Difficulty: easy

Adolf Hesse: Easy Preludes
Nineteenth-century German organ music has a reputation for being, if contrapuntally correct, perhaps a bit stodgy and uninspired. Better composers of the era, however, wrote some perfectly serviceable music. This collection by Hesse is a good place to start, being designed with students in mind. (The fingerings and pedalings in this collection, by the way, are good: you should use them!) Difficulty: easy

Felix Mendelssohn: Six Sonatas, Op. 65
One can say, without any hyperbole, that Mendelssohn was the greatest German organ composer of his century, and that these six sonatas represent the summit of his output for the instrument. They are terribly useful for recitals — they work on just about any kind of instrument — and nearly all of the individual movements can be excerpted for use as service music, too. Difficulty: easy to difficult

Gustav Merkel: Twelve Organ Pieces, Op. 102
Much like the works of Hesse, I don't find these to be especially inspired, but they are easy enough, short enough, and compositionally sound. Merkel's other collections of organ music are much the same. Difficulty: easy

Johann Pachelbel: Preludes, Toccatas, Fantasias, Fugues, and Ricercars
These selected freely-composed works are a good assortment of pieces suitable for preludes or postludes. In the context of American liturgies, the more serious contrapuntal works (particularly the ricercars and longer fugues) serve well as preludes; the toccatas, in particular, can make for short, showy, and effective postludes. Difficulty: easy to moderate

Max Reger: Twelve Pieces for Organ, Op. 59
Reger is not a particularly accessible composer for inexperienced organists, but this collection has all his best freely-composed pieces for beginners. The Benedictus (No. 9) may be Reger's most-performed work, while the Toccata and Fugue (Nos. 5-6) are probably Reger's easiest prelude/fugue pairing. Difficulty: moderate to difficult

Josef Rheinberger: Twelve Trios, Op. 49
These pieces are a good place to start if you're new to playing trio textures, and they can work as pleasant, short preludes or postludes. Difficulty: easy to moderate

Charles Villiers Stanford: Six Short Preludes and Postludes, Op. 101
Stanford is a notoriously fiddly composer: I find it difficult to play anything he wrote fluently without a good deal of work. (Perhaps this mirrors his difficult personality.) But these six pieces are well-worth the effort. No. 2 of the collection is a rousing postlude, and No. 6 (based on St. Columba, "The King of Love my Shepherd Is") suggests Stanford's lyrical side. Difficulty: moderate to difficult

John Stanley: Voluntaries, Opp. 5, 6, and 7
For some reason Stanley is pooh-poohed by many serious (read: academic) organists, but I find his output to be both practical (it is all manuals-only, and generally quite thin, texturally) and compositionally defensible. These are some of the very first pieces I would recommend to beginning organists looking for service music. Difficulty: easy

Louis Vierne: Twenty-Four Pieces in Free Style, Op. 31
This charming selection of pieces, originally composed for harmonium, is an invaluable resource: Vierne's harmonic language provides welcome variety, and the pedaling in this collection poses few, if any, challenges. I particularly recommend the Berceuse (No. 19), Arabesque (No. 15), Lied (No. 17), and Carillon (No. 21) — which is one of my favorite postludes. Difficulty: moderate

The above suggestions are a good place to start, but there is scarcely a limit to the variety of organ repertoire one might suggest. Consider also Buxtehude praeludia (which vary widely in length, complexity, and difficulty), or some of the easier Bach preludes and fugues (BWV 533 or BWV 549, to start). Jean Langlais has a variety of organ compositions, of varying quality, but you could start with his Organ Book, Op. 91. The English keyboard school (Byrd, Gibbons, Tomkins, in particular) offers much in the way of manuals-only voluntaries. The charms of French classical organ music, on the other hand, are so heavily reliant on the particular colors of the French classical organ that I cannot in good conscience recommend the genre for most American organists.
