Top 15 Most Influential Classical Composers

Classical music has been a lifelong passion of mine, and I’ve dedicated countless years to its study. When someone proposed the idea of creating a list of the most influential classical composers, I was initially hesitant but ultimately took on the challenge. While I’m confident in my selections, I acknowledge that this list may spark debate. Instead of ranking them by importance—an inherently subjective task—I’ve arranged them in chronological order.

15. Saint Hildegard Von Bingen 1098 – 1179

Hildegard Von Bingen, often regarded as the mother of opera due to her groundbreaking work *Ordo Virtutum*, was a true polymath. Her expertise spanned numerous fields, including theology, natural science, medicine, philosophy, and the arts. As a German abbess, she authored influential texts, composed liturgical music, penned poetry, and even created the first surviving morality play. Her visionary contributions to vocal music laid the foundation for Renaissance compositions and opera. Though not formally canonized, she is widely venerated as a saint, with her feast day celebrated on September 17. If I had to name one figure whose impact on classical music stands above all, Hildegard Von Bingen would undoubtedly be a top contender.

Dufay, a Franco-Flemish composer and music theorist, was a pivotal figure in the early Renaissance and the Burgundian School. Renowned as Europe's most celebrated and influential composer during the mid-15th century, he bridged the gap between medieval and Renaissance music. While he employed medieval techniques like isorhythm, he also pioneered the use of harmonies, phrasing, and expressive melodies that defined the early Renaissance. Widely regarded as the greatest composer of his era, his legacy continues to endure to this day.

The Kyrie from Palestrina’s *Missa Papae Marcelli* is thought to have been composed for the Council of Trent, which began on December 13, 1545. Its purpose was to persuade the Cardinals, Bishops, and Pope to retain polyphonic music in church services. The council not only accepted it but also elevated it, alongside Gregorian Chant, as the official music of the Roman Catholic Mass—a decision reaffirmed during the Second Vatican Council in the 1960s. Palestrina is celebrated as the master of polyphony, and his compositions were considered unparalleled during his lifetime and for centuries afterward. His work remains the pinnacle of this musical style.

Regrettably, the only high-quality clip available features Nigel Kennedy, whose style I find unappealing. In this performance, Kennedy plays a segment from *The Four Seasons*, a set of four violin concertos that stand as Vivaldi’s most famous composition and a beloved Baroque masterpiece. Vivaldi is credited with helping to transition Baroque music, known for its dramatic contrasts, toward the classical style. His work profoundly influenced Johann Sebastian Bach, particularly in the realms of concertos and arias.

I’ve chosen Handel’s *Largo (Ombra mai fu)* from his opera *Xerxes* over the more widely known *Messiah*, as it is a lesser-heard yet profoundly moving aria. Handel, inspired by the techniques of Italian Baroque masters and Henry Purcell, left an indelible mark on subsequent composers like Haydn, Mozart, and Beethoven. His contributions were instrumental in bridging the Baroque and Classical periods.

CPE Bach enjoyed immense acclaim during the latter half of the 18th century. Mozart famously remarked, “He is the father, we are the children,” while Haydn credited much of his musical education to studying Bach’s works. Beethoven also held him in high esteem. Bach’s keyboard sonatas, in particular, represent a pivotal moment in the evolution of musical form.

Haydn is widely celebrated as the father of both the symphony and the string quartet. In the clip above, you can listen to the 4th movement of his *Kaiser String Quartet (Op.76 No.3)*. A lifelong Austrian resident, Haydn spent the majority of his career as a court musician for the affluent Esterházy family on their secluded estate. Cut off from other composers and musical trends for much of his life, he famously remarked that this isolation “forced him to become original.”

Mozart’s prolific career produced over 600 compositions, many of which are considered masterpieces in symphonic, chamber, operatic, and choral music. He remains one of the most beloved classical composers, with numerous works featured in standard concert repertoires. In this clip, Sumi Jo performs the iconic *Queen of the Night* aria.

I was privileged to attend a performance of *Aida* at the Verona Arena for my birthday in 2005, but I’ve chosen to share the *Dies Irae* from his *Requiem*. Verdi stands as one of the most impactful Italian opera composers of the 19th century, surpassing the contributions of Bellini, Donizetti, and Rossini. His operas are staples in theaters worldwide, transcending the confines of the genre. While some critics argue that his music appealed to popular tastes with its diatonic style and melodramatic flair, Verdi’s masterpieces remain central to the operatic repertoire even 150 years after their creation.

Wagner’s later works are renowned for their intricate contrapuntal textures, rich chromatic harmonies, and masterful orchestration. He extensively used leitmotifs—musical themes tied to characters, settings, or story elements. Wagner’s innovations, such as extreme chromaticism and rapid shifts in tonal centers, profoundly shaped the evolution of European classical music.

5. Gustav Mahler 1860 – 1911

As a pivotal figure of the late Romantic era, Mahler significantly influenced the Second Viennese School, including Schoenberg, Berg, and Webern. His impact extended to later composers like Britten, Copland, and Shostakovich. Interestingly, some composers, such as Stravinsky and Vaughan-Williams, rejected his style, with Stravinsky mockingly calling him “malheur” (meaning misfortune). Despite this, Mahler’s legacy inspired Richard Strauss, Kurt Weill, Leonard Bernstein, and Alfred Schnittke.

4. Igor Stravinsky 1882 – 1971

The premiere of *The Rite of Spring* sparked a riot in the opera house. The clip above features the first 10 minutes, possibly conducted by Stravinsky himself, known for his slower tempos. I highly recommend watching the entire clip, as it faithfully recreates the original ballet performance with Nijinsky’s choreography. Before this groundbreaking work, audiences were accustomed to traditional ballets like *Swan Lake* with their elegant tutus and melodic scores.

3. Edgard Varese 1883 – 1965

Varese, often hailed as the “Father of Electronic Music,” revolutionized sound through his innovative use of new instruments and electronic techniques. Henry Miller famously dubbed him “The stratospheric Colossus of Sound.” His influence extended to composers like Harrison Birtwistle, Pierre Boulez, John Cage, Morton Feldman, and Frank Zappa, among others. The piece *Ionisation*, featured above, is particularly notable for inspiring Zappa’s own musical journey.

2. Nadia Boulanger 1887 – 1979

While I couldn’t locate a clip of Nadia Boulanger’s music, I’ve included a piece by her sister Lili, titled *Clairières dans le ciel: Nr. 7 “Nous nous aimerons tant.”* Lili, Nadia’s first student, made history as the first woman to win the Prix de Rome in 1913. Nadia Boulanger’s legacy lies not in her compositions but in her unparalleled influence as a teacher. Her students include luminaries like Leonard Bernstein, Aaron Copland, Philip Glass, and George Gershwin, cementing her as one of the 20th century’s most impactful figures in music.

1. John Cage 1912 – 1992

The piece above is *Sonata V* for prepared piano, a technique where objects like erasers and screws are placed between the piano strings to create a more percussive sound. As demonstrated in the clip, this method allows for a diverse range of unique tones. Cage is perhaps best known for *4’33”*, a composition where performers remain silent, highlighting the beauty of ambient sounds in everyday life.

Bonus: Henry Purcell 1659 – 1695

Purcell is included as a bonus due to his far-reaching influence, extending beyond classical music to rock. As noted by Wikipedia, Purcell’s impact is evident in modern rock, with Pete Townshend of The Who citing him as an inspiration, particularly in *Pinball Wizard*. Additionally, his *Music for the Funeral of Queen Mary* features in *A Clockwork Orange*. Above, you can listen to Jessye Norman’s exceptional rendition of *Dido’s Lament* from Purcell’s opera *Dido and Aeneas*.

Afterword

You may have noticed the absence of J.S. Bach from this list. While Bach is undoubtedly one of history’s greatest composers, his influence on subsequent generations was limited. In his lifetime, he was celebrated as an organist but seen as old-fashioned in his compositional style. His mastery brought the Baroque era to its peak, yet his impact on later musical developments was minimal.
