Johann Joachim Quantz was the most innovative performer and composer for the flute in the eighteenth century. He was also the teacher, composer and flute-maker to Frederick II, ‘The Great’, King of Prussia. Royal concerts were the principal venue for Quantz’s concertos where their constant invention and brilliance were intensified by his specially designed flutes. The A minor Concerto has only recently been retrieved from the Russian National Library in St Petersburg, whilst the G major’s cadenzas have been preserved, fully written-out, providing a valuable direct link to performance practices in Quantz’s time. Poignantly, Frederick himself completed the C minor Concerto after Quantz’s death.

The BIS Complete Edition of the CPE Bach Keyboard Concertos with this disc reaches Volume 12, and is by now firmly established as a major contribution to the repertoire. These are performances which have received great acclaim, for instance Volume 10 (CD914) which Diapason described with the words: 'Spányi and his orchestra speak the language of Carl Philip as one speaks one's mother tongue, bringing out nuances, voices and contrasts without ever overstating the effects.' the whole series has been greeted as 'fascinating' and 'constantly surprising' (in Répertoire), 'very important' (classicstoday.com), 'splendid' (Fanfare) and being of 'an exceptionally high standard' (Diapason). For this volume, a sonatina and a concerto from the early 1760s have been brought together with a concerto from 1746.

In the latest volume of his highly regarded series, Miklós Spányi has assembled a varied programme, showing different aspects of C.P.E. Bach and the context in which he was active. Two sets of variations are included, both of them intended for the rapidly growing market created by the increasing number of skilled amateur players. Such sets would typically be based on a popular song - such as 'Ich schlief, da träumte mir' ('I slept, and then I dreamt'), used by a number of Bach's contemporaries - and were often printed in periodical anthologies of music by different composers. In contrast to these more intimate pieces, the Sonata in E flat major and, even more so, the Sinfonia in F major, are examples of the orchestral style of writing that Bach at times allowed to spill over into his keyboard works. The Sinfonia is indeed an arrangement of his own symphony for orchestra, Wq 181. Two other, short pieces, both dated 1760 are included on the disc, one of which, Allegro in C major, was originally intended for use in a 'Spieluhr' (a musical box or clock) - a genre in which both Bach's father, Johann Sebastian, and Handel had written, and for which the young Beethoven would also compose. For a large number of discs in this series, Spányi has chosen to play on a clavichord - an instrument loved by Bach. Volume 17 is a case in point: selected as an Editor's Choice in Gramophone, the disc was described as 'the answer to clavichord fans' dreams'. For the present programme, however, Spányi has elected to perform on a tangent piano, a variant of the fortepiano with a number of possibilities for adapting the timbre and dynamics. The results are striking especially in the sets of variations, but also in the more 'orchestral' pieces with their rich timbres and dynamic contrasts.

In a series that has been called "very important" (Classics Today.com), "of an exceptional level" (Diapason), "always surprising, and certainly ideal" (Répertoire) and "deeply sympathetic" (International Record Review), Miklòs Spànyi has reached the 13th volume, featuring one concerto and two sonatinas for keyboard and orchestra - a genre which, according to the informative liner notes by C.P.E. Bach scholars Jane R. Stevens and Darrell M. Berg, arose as "a direct effort to provide music for a growing concert-going musical public". As might be expected, these are works of immediate appeal, with those trademarks of their composer: the unceasing spirit of innovation and the highly individual use of rhythm and keys. (The opener on this disc is the Sonatina in F major - which actually starts in d minor: a strategy that increases the major mode's feeling of brightness when it belatedly appears.) For those of you who haven't yet discovered the wonderful world of C. P. E. Bach's keyboard works, this is a good place to start; for those who have, prepare yourself for a generous hour of sheer enjoyment!

Described in Gramophone as ‘one of the most needed and important recording projects in progress today’, this series has up until now featured the clavichord, the tangent piano, and the fortepiano. It is therefore something of an occasion when Miklós Spányi for his Volume 37 chooses to perform on a harpsichord. In doing so he reminds us of C.P.E. Bach’s own advice to keyboard players to have both a clavichord and a harpsichord in order to play ‘all sorts of things alternating’ (‘allerley Sachen abwechselnd’). But the album – which includes some of the composer’s earliest works – also features one of the very few, if not the only, compositions that Bach specifically dedicated to the harpsichord, namely the Sonata per il cembalo a 2 tastature. In it, Bach makes colorful use of the instrument by specifying various detailed and idiosyncratic harpsichord registrations. Spányi also performs two of the few fugues – in F and A major respectively – that Carl Philipp composed: besides the general shift in fashion away from intricate counterpoint to melodic simplicity, it is possible that he found father Johann Sebastian’s achievements in that particular genre too hard an act to follow.

This new release is the latest installment in Miklos Spanyi’s series of the keyboard music of Carl Philipp Emanuel Bach. The works on this volume include some of CPE Bach’s most celebrated works. The six collections “fur Kenner und Liebhaber” were published between 1779 and 1787. Roughly translated as “connaisseurs and amateurs,” the collections were composed for the enjoyment of both the musically trained and untrained. Spanyi has decided to combine works from both collections for this volume, and performs them on the clavichord. The next volume will complete these collections, and will be performed on the tangent piano. Spanyi’s prior installments in this series have been called an “illuminating journey through the keyboard landscape of JS Bach’s best-known son” (BBC Music Magazine) and “one of the most needed and important recording projects in progress today.” (Gramophone)

On this amply filled album, Carl Philipp Emanuel Bach’s Clavierstücke verschiedener Art (Keyboard Pieces of various Kinds) is presented in its entirety, with the exception of three songs for voice and keyboard. This collection is the most diverse of Bach’s publications and includes multi-movement genres, a free fantasia, a learned fugue, and various short pieces of varying degrees of difficulty. The variety suggests that Bach did not want for his keyboard music to be strictly divided into ‘light’ and ‘serious’ pieces. But he also wished to demonstrate a wide range of techniques of keyboard composition and performance: orchestral writing in the symphony and the concerto, two-part textures in the sonata, polyphony in the fugue, and free and virtuosic composition in the fantasias and solfeggios. In order to bring a similar variety to his recording of the collection, Miklós Spányi has chosen to perform the pieces on a harpsichord built after the Antwerp maker Joannes Daniel Dulcken. To this double-manual harpsichord offering a wide range of possible registrations, Spányi has added a so-called swell device which facilitates quick dynamic changes. This makes it possible to bring out the contrasts between orchestral and soloistic textures in the Concerto in C major, but also to highlight the different characters in the contrasting pairs of Minuets.

As Carl Philipp Emanuel Bach published successive collections of the Kenner und Liebhaber series, he explored new genres and styles. In the second collection he added his idiosyncratic rondos, and in the fourth he included free fantasias. The fifth collection, composed between 1779 and 1784, contains no new genres, but displays more variety in terms of textures and thematic ideas than any of the previous volumes. In fact, Bach’s preoccupation with variation is almost obsessive – it is as if he cannot finish phrases without varying either texture, tonality, rhythmic pulse or dynamics. To the six Sonatas, Rondos and Fantasias that make up the collection, Miklós Spányi adds two independent works. Bach initially composed 17 variations on the folk-like tune Ich schlief, da träumte mir in 1752 (included in Vol. 19 of this series) but returned to it almost twenty years later, publishing seven new variations. Closing the album is another set of variations, now on an original theme, an Arioso sostenuto in A major. Miklós Spányi began his survey of the Kenner und Liebhaber collections on the clavichord but the following releases have featured the tangent piano. And 35 albums into this monumental series, individual volumes are still being warmly greeted, for instance on EarlyMusicReview.com where the reviewer of Volume 32 (BIS-2205) professed to be ‘invariably struck not only by the originality of C. P. E. Bach’s keyboard writing, but also the high level of performance consistently maintained by Miklós Spányi.’

This disc completes the set of CPE Bach’s Fortsetzung Sonatas, Wq51 that began in Volume 26 in this series. Although the sonatas were not published together with the composer's own variants on them, such alternative versions exist in manuscript, and splitting this set of large-scale works over two discs, Miklós Spányi also includes recordings of these varied or embellished versions that may represent the composer's revisions but could equally well have been intended as study material for his students.
