„The vocal quar­tet sang with solistic colours and its very uni­fied, balan­ced ensem­ble sound.”

Cà4 – con­so­nanz à 4

They come from the rug­ged Antrim coast, the end­less hori­zons of Eas­tern Fries­land, the pic­tures­que artists vil­la­ge of Worps­we­de and the bar­ren Swa­bi­an Albs. They have appeared in Isra­el, Spain, Ita­ly, Fran­ce, Eng­land, Rus­sia, Croa­tia, Nor­way, Swe­den, Fin­land, Switz­er­land, Aus­tria, Nami­bia, South Afri­ca and throughout Ger­ma­ny. They have per­for­med grand ope­ra, lute songs, con­tem­pora­ry music with exten­ded vocal tech­ni­ques, roman­tic lie­der reci­tals, ear­ly music and music theat­re and have per­for­med high mas­ses in gre­at cathe­drals. Some­whe­re along the way they met.

They sing with pas­si­on and as a quar­tet, enjoy the free­dom to sing music that is clo­se to their hearts. With their indi­vi­du­al inter­pre­ta­ti­on, refi­ned in inten­si­ve rehe­ar­sals, they express their dedi­ca­ti­on and devo­ti­on and share it with their audience.

Each mem­ber of the quar­tet brings their own spe­cial ingre­dients, for­med by the influ­ence of many gre­at musi­ci­ans throughout each individual’s pro­fes­sio­nal career.

Com­bi­ning this with the various inte­rests and stu­dies- oboe, flu­te, organ, acting and lite­ra­tu­re — pro­vi­des a rich pala­te of expe­ri­ence to draw on when­ta­king a pie­ce apart, the all important crea­ti­ve pro­cess whe­re a fresh approach is sought even for old favourites.

They are as at home in reper­toire of the lar­ger cho­ral works of Bruck­ner Liszt, Ver­di or Pou­lenc as with pie­ces writ­ten for four voices.

Once they are immer­sed in a pie­ce, the hours fly by – con­stant­ly on the loo­kout for a new, indi­vi­du­al approach. The inter­pre­ta­ti­on of a pie­ce is in flux; always chan­ging, gro­wing and stay­ing ali­ve. Dyna­mics and tem­po are varied and adap­ted to suit the atmo­s­phe­re and occa­si­on, always in clo­se con­ta­ct with the audi­ence. Having worked and tra­vel­led tog­e­ther for a num­ber of years, they have beco­me well attu­n­ed to each other and work well as a team, which ispar­ti­cu­lar­ly bene­fi­cial when sin­ging ora­to­ri­os together.

Wil­trud de Vries, Annet­te Gut­jahr, Bern­hard Schef­fel and All­an Par­kes are their own instru­ment, a uni­fied body of sound made up of four dif­fe­rent cha­rac­ters who com­bi­ned for­ces with ver­ve and enthu­si­asm to focus on their com­mon goal of per­forming qua­li­ty vocal music with vitality.

They are con­so­nanz à 4.



Cà4 – „Maria“

The “Maria” pro­gram­me is one of the the quartet´s most suc­cess­ful pro­jects. It focu­ses on com­po­si­ti­ons on the the­me of Mari­an wor­s­hip and is an inte­gral part of their reper­toire. It was ori­gi­nal­ly desi­gned for a con­cert cele­bra­ting the Assump­ti­on of the Vir­gin Mary in 2008 at the Ein­sie­deln Monas­te­ry of Pil­grimage (Switz­er­land). Encou­ra­ged by the over­whel­ming respon­se, the quar­tet fre­quent­ly repeated the pro­gram­me beco­m­ing immer­sed in the the­me and deve­lo­ping their inter­pre­ta­ti­on and per­for­mance. The pro­gram was given addi­tio­nal refi­ne­ment during the making of the CD Maria in 2013 in the cathe­dral of Keve­la­er in Germany.

It is par­ti­cu­lar­ly fasci­na­ting how dif­fer­ent­ly the indi­vi­du­al com­po­sers trea­ted the sub­ject mat­ter: Stravinsky’s pray­er is simp­le and mat­ter-of-fact, while Poulenc’s set­ting is inti­ma­te and expres­si­ve , Liszt’s pray­er is a rosa­ry las­ting several minu­tes with recur­ring motifs, and Verdi’s work is an enig­ma­tic sca­le har­mo­nis­ed for four mixed voices resul­ting in a com­plex and dra­ma­tic composition. 

Our Father

Fol­lowing their suc­cess­ful Maria Pro­gram­me, con­so­nanz à 4 deve­lo­ped  “Vater Unser” which is  named after the ope­ning words of the Lord’s Pray­er. It explo­res rich and sono­rous spi­ri­tu­al com­po­si­ti­ons that revol­ve around sal­va­ti­on, peace and inti­ma­te pray­er. Da pacem by Pärt, Vater Unser and Psalm 139 by Leh­nen, Letz­te Bit­te by Wolf, Abend­frie­de by Rhein­ber­ger, Chris­tus fac­tus est by Bruck­ner, as well as pie­ces by Par­ry and Men­dels­sohn take the lis­tener on an inward, reflec­ti­ve jour­ney through the warm sound­ing, some­ti­mes ten­der, some­ti­mes power­ful moments in the­se sac­red compositions.

Flo­re­te Flores

“Blossom, you flowers, like the lily, emit fra­gran­ce and bring forth lea­ves with grace. Sing tog­e­ther a hymn of prai­se and bless the Lord in all his works” (Jesus Sirach, chap­ter 39, ver­se 19) 

Flo­ret flo­res” is the name of the colour­ful and varied a capel­la pro­gram­me with which con­so­nanz à 4 pres­ents a rich cross-sec­tion of their work. It is named after a com­po­si­ti­on of the same name which Elmar Leh­nen wro­te for the quar­tet in 2013. The pro­gram­me inclu­des lively and flu­ent­ly nar­ra­ted images of natu­re, calm and deep pray­ers, catchy melo­dies as well as com­plex har­mo­nies. Work by com­po­sers like Pärt, Elgar, Fin­zi, Dys­on, Men­dels­sohn, Leh­nen, Par­ry or Wolf pro­mi­se a lively and varied con­cert evening.

“A Cap­pel­la sin­ging at such a high level is rare­ly heard. The dia­lo­gue bet­ween the sin­gers is cap­ti­vat­ing in its natu­ral­ness. The ensem­ble shows sub­t­le­ty and intui­ti­on for the smal­lest chan­ges in dyna­mics, colour and har­mo­ny. The sac­red state­ment of faith bey­ond the pure musi­cal text is con­vey­ed with inti­ma­cy, moving each indi­vi­du­al song in its ent­i­re depth. This is trans­mit­ted direct­ly to the audi­ence, crea­ting an inten­se bond in the shared experience.

Mul­ti­fa­ce­ted in full­ness of tone, warm­th and dyna­mics, ‘con­so­nanz à 4’ shows a filigree sound with a spe­cial charm.”

Blech­mann, Ahlen — Review of the con­cert on 7.10.2017

Christ­mas Carols


christ­mas carols

christ­mas carols is con­so­nanz à 4’s suc­cess­ful Christ­mas pro­gram, which is also avail­ab­le on CD. A colour­ful com­bi­na­ti­on of cheer­ful and con­tem­pla­ti­ve melo­dies with tra­di­tio­nal old favou­rites and­les­ser well known gems, set in Eng­lish by various com­po­sers. Carols by Charles Wood, Wal­ford Davies and Arthur Sul­li­van among others, have a fresh­ness and cla­ri­ty when sung by the four unac­com­pa­nied voices. Fur­ther high­lights in the pro­gram inclu­de: Vaug­han Williams’s“The Bles­sed Son of God”, “The Crown of Roses” by Tschai­kow­sky, and the atmo­s­phe­ric “In the Bleak Mid­win­ter” by Gus­tav Holst. Andrew Carter’s lil­ting arran­ge­ment of the Appa­la­chi­an Folk­song “I Won­der as I Wan­der” and Her­bert Howels’s “Here is the litt­le door”, which is both evo­ca­ti­ve and a strident batt­le cry are rare gems in the delight­ful collection.


The pro­gram­me is also avail­ab­le with  a selec­tion of sea­so­nal readings.


You can look for­ward to a par­ti­cu­lar­ly atmo­s­phe­ric musi­cal evening.

“San­ges­freu­de und Dis­zi­plin, dazu die akzent­freu­di­ge Arti­ku­la­ti­on,
gepaart mit lyri­scher Emotionalität…”

– Hei­den­hei­mer Zei­tung,  02.10.2019


„Höhe­punkt des Kon­zer­tes waren die A‑cap­pel­la-Minia­tu­ren des Solis­ten­quar­tetts …Liszts „Ave ver­um“ und erst recht Elmar Leh­nens „Sta­bat Mater“ offen­bar­ten ihren ganz eige­nen Har­mo­ni­en­reich­tum und das traum­haf­te Ver­ständ­nis von „con­so­nanz à 4″. Wie wäre es ein­mal mit einem gan­zen Kon­zert des Vokalensembles?“

– Nor­bert Duwe für die Nordsee-Zeitung

“…Ob hin­ge­gen Liszt, Elgar, Pou­lenc, Pärt oder Ver­di: Sie alle beto­nen kom­po­si­to­risch im Zusam­men­hang mit Maria vor­wie­gend das Mys­ti­sche, das dem Welt­en­tru­bel Ent­rück­te, aber glei­cher­ma­ßen zutiefst Sinn­li­che, Tröst­li­che. Dies zu unter­strei­chen gelang dem Gesangs­quar­tett auf fas­zi­nie­ren­de Wei­se. Ange­nehm mode­ra­te Tem­pi und fein dosier­te dyna­mi­sche Wech­sel ver­mit­tel­ten eine stim­mungs­vol­le Atmosphäre.”

Weser Kurier, Juni 2012



Der Wind heult, die Doh­len zwit­schern, in der Fer­ne klingt eine Glo­cke – alles das ist lei­se im Hin­ter­grund zu hören, wenn man sich in den Gesang des A‑cap­pel­la-Quar­tetts con­so­nanz à 4 und das Orgel­spiel Elmar Leh­nens ver­tieft und gibt der CD den Cha­rak­ter einer Live-Aufnahme.
