La Speranza is a group of string and wind players that bring chamber music performances on period instruments of repertoire spanning from the Baroque to early Romantic eras. Named after the Italian word for “hope”, La Speranza seeks to promote physical and emotional healing through their historically informed performances in Houston communities.

Each of our musicians have made historically informed performance practice (HIPP) a focus of their careers and are active performers in the United States and Europe. We present 3-4 formal concerts a year, as well as several free concerts in local hospitals and community centers.


Thomas Carroll, clarinet


With a sound described as “beautifully warm” (Herald Times) and “sweet and agile” (New York Times), period clarinetist and instrument builder Thomas Carroll performs extensively throughout North America and Europe on historical instruments. He holds degrees from Oberlin Conservatory, Indiana University, and The Royal Conservatoire of The Hague, where his major teacher on early clarinets and chalumeaux was Eric Hoeprich.

Internationally, Thomas has performed under such directors as Christophe Coin, Richard Egarr, Philippe Herreweghe, Jos van Immerseel, Allessandro Moccia, and David Stern; and has performed at numerous festivals as an orchestral and chamber musician including Oude Muziek Utrecht, Muziekzomer Gelderland, Young Euro Classic, Festival de Saintes, and Musica Antiqua Brugge in venues ranging from the Kozerthaus in Berlin to the Concertgebouw in Amsterdam. He has been featured as a concerto soloist with Lyra Baroque, Ensemble ad Libitum, and Grand Harmonie to critical acclaim. In North America, Thomas is the principal clarinetist with Boston-based Grand Harmonie and Houston-based Mercury: The Orchestra Redefined, and frequently collaborates with other early music specialists on the east coast including the Clarion Music and Handel and Haydn Societies and Boston Baroque. He has given faculty chamber recitals and guest lectures and masterclasses on both coasts and at the Hawaii Performing Arts Festival. Thomas is currently on the faculty of the Brookline Music School and maintains a private studio.

An interest in instrument mechanics and acoustics has led Thomas to a secondary career as an instrument builder and extensive research into 18th and 19th century wood treatment and seasoning. He studied woodworking and instrument construction with Linda Shortridge, Rob Turner, and Paul Beekhuizen, and builds chalumeaux, baroque, and classical clarinets, and basset instruments for use in historically-informed performance ensembles.


Dr. Mario Aschauer, fortepiano


Praised a performer with “unconventional ludic drive” by the press and listed among Austria’s thirty-five most outstanding researchers aged under thirty-five by the Austrian Science Fund in 2013, Mario Aschauer works as conductor, harpsichordist, and musicologist at the interface of music scholarship and performance.

His book on German Keyboard Treatises in the Second Half of the Eighteenth Century (Kassel: Bärenreiter, 2011) is considered a standard reference in the field. Further projects in early keyboard studies include the development of historical-style keyboard fingerings and notes on performance practice for new editions of prominent works by Beethoven and Schubert as well as a new edition of Mozart’s keyboard sonatas published by Bärenreiter.

As a performer on historical keyboard instruments Mario has built up a diverse repertoire specializing in Austrian Baroque music. He is member of the Calamus-Consort, which won first prize at the International H.I.F. Biber Competetion in 2009 and since then has been invited to numerous renowned early music festivals such as Resonanzen Wien, Bach Fest Leipzig (Germany), and Itinéraire Baroque en Périgord Vert (France). Their CD “Un dolce affanno” (Passacaille, 2012) features highlights from operas performed at the Vienna court around 1700 with chalumeau, clarinet, and harpsichord as solo instruments.

Having earned a degree in conducting from the Linz Bruckner Conservatory at the young age of seventeen, Mario had already conducted major works from the choral and symphonic canon before he graduated from high school. Shortly thereafter Mario began to specialize in the music of the late eighteenth century performed on period instruments with his Ensemble NovAntique Linz. Their repertoire is typically beyond the standard and includes large-scale sacred and symphonic works and oratorios by composers such as Gassmann, Gossec, Kraus, Salieri and Wagenseil. In addition, Mario also collaborates with other early music ensembles such as Progetto Semiserio Vienna, Harmony of Nations Baroque Orchestra, Ars Antiqua Austria, and L’Orfeo Baroque Orchestra, Ars Lyrica Houston, Houston Bach Society, and Mercury Houston.

Mario has edited Schubert’s opera fragment Adrast, D. 137, for the New Schubert Edition and gave it its world premiere in Vienna in 2010. The recording of the concert was broadcast on BBC Radio and won the “Pasticcio Prize” from the Austrian Broadcasting Corporation (ORF). Mario’s current research for a new book on Anton Bruckner’s creative process was selected for prestigious fellowships from the Austrian Science Fund and the Max Kade Foundation, Inc. (New York). The project also entails a recording of selections from Bruckner’s sketches on a mid-19th-century fortepiano similar to the composer’s own instrument. Mario is member of the advisory boards of the New Bruckner Complete Edition (Vienna) and the Anton Bruckner Institut Linz.

As Assistant Professor of Music Mario teaches music history, historically informed performance and early keyboard instruments at the Sam Houston State University School of Music (Huntsville, TX). He holds an MA in harpsichord performance from the University of Music and Performing Arts, Vienna, an MPhil and a PhD in musicology from the University of Vienna—all of which he earned “with distinction”—as well as a degree in conducting from the Linz Bruckner Conservatory. He has since returned to teach at these institutions. Between 2008 and 2014 Mario held a position as researcher at the Austrian Academy of Sciences (Vienna). In 2012/13 he was a postdoctoral fellow and visiting guest lecturer at the Yale School of Music.

Andrew Schneider, keyboard


A Houston native, Andrew Schneider is a pianist, harpsichordist, organist, conductor, composer, music copyist, vocal and instrumental coach. He obtained his B.Mus. in composition at Rice University. In 2009, he was a finalist in the ASCAP Morton Gould Young Composers Competition. His compositions, including a growing body of music for educational-level ensembles, evince his complete faith in the relevance of traditional musical aesthetics and forms, in the conservative spirit of “reality being infinitely more interesting than fiction.” He thus considers it essential to be a well-informed musical citizen about all aspects of the concert music tradition. Throughout this, he is avidly interested in understanding music intrinsically, rendering it relevant to the present age.
To that end, Andrew considers being an active performer a key part of being an informed composer. Among his most formative influences in the realm of performance has been Thomas Jaber, whose effortless finesse in providing supportive accompaniment has rubbed off well, especially in the art of realizing continuo from figures. Since 2012, Andrew has been playing harpsichord continuo with period instrument ensemble Mercury Houston, including as part of the Texas Early Music Festival since 2014. He has also played Handel’s Messiah with the San Antonio Symphony and the Kingwood Chorale, and Haydn’s Creation with the Woodlands Chorale.
From 2012-16, Andrew served as organist at St. Michael Catholic Church in Houston, and since then has been an active church organist throughout the Houston area. Likewise, he has been a staff accompanist at LSCS-Kingwood since 2014. Recently, Andrew made his music directorial debut in Sweeney Todd and Rita, and his operatic coaching debut in Ariadne auf Naxos. He has also coached the leading role in Die schweigsame Frau for a 2016 Pittsburgh production. In his spare time, Andrew enjoys history, literature, linguistics, cartography, and murder mysteries.
