Let’s delve into the prolific life and influential works of Johann Sebastian Bach


1. Bach’s Early Life

Born in Eisenach on 21st March 1685, Johann Sebastian Bach was the youngest child of Maria Elisabeth and Johann Ambrosius Bach. His father, the director of the town musicians, introduced him to the violin and harpsichord at a young age.

The Bach family was deeply rooted in music, with many of Bach’s uncles serving as professional musicians, including church organists, court chamber musicians, and composers. One of his uncles, Johann Christoph Bach, played a critical role in introducing him to the organ.3

The death of his parents around his tenth birthday was a turning point in Bach’s life. He moved in with his eldest brother, an organist at a local church, where he began copying music. This period provided him with valuable instruction on the clavichord. It exposed him to the works of great composers of the day, such as Johann Pachelbel.

Despite his fame today as one of the greatest composers of all time, Bach’s contemporaries primarily admired him as an outstanding harpsichordist, organist, and expert on organ building.


2. Bach’s Early Musical Journey

The early musical journey of Johann Sebastian Bach is an intriguing exploration of talent, passion, and dedication. It all started at Saint Michael’s School in Lüneburg, where young Bach was exposed to the world of music.

This laid the foundation for his future genius.

Bach at Saint Michael’s School in Lüneburg

  • At Saint Michael’s School in Lüneburg, Bach began his musical journey as a chorister.
  • The school provided him with not only a strong academic education but also exposure to a vast range of musical experiences.
  • Studying under Georg Böhm, a renowned organist at the time, he honed his skills in choral singing, instrumental playing, and even composition.
  • His exposure to the rich organ heritage of northern Germany and his interaction with other accomplished musicians like Johann Adam Reincken in Hamburg significantly shaped his musical style.

Role as Organist at the Blasius Church in Mühlhausen

After his time in Lüneburg, Bach journeyed to Mühlhausen, where he served as an organist at the Blasius Church. This phase of his career was characterized by a deep exploration of keyboard music, with a particular focus on the organ.

Here, Bach had the freedom to experiment with his skills. Though at times his innovative harmonizing of hymn tunes caused some friction with the congregation who found it challenging to sing along to his accompaniment. Nevertheless, his tenure at Mühlhausen solidified his reputation as a gifted organist and budding composer.

Challenges During This Period

This period was not without its challenges, however.

  • Bach’s high standards led to conflicts with local singers and instrumentalists, culminating in a public scuffle with a bassoon player.
  • Yet, despite these issues, his employers were reluctant to dismiss him, recognizing his exceptional ability.
  • It was during this tumultuous period that Bach began experimenting with traditional forms and hymns of the orthodox Lutheran service.
  • He incorporated them into his compositions and thereby creating a unique blend of styles.

In sum, Bach’s early musical journey was marked by both struggle and triumph. His experiences at Saint Michael’s School and the Blasius Church in Mühlhausen played pivotal roles in shaping him into the musical genius he eventually became.

Today, we remember him not just as a composer, but as an innovator who transformed the landscape of Baroque music.

Bach’s Compositions in Mühlhausen

During his time in Mühlhausen, Bach composed numerous pieces. But it was his church cantatas that left a lasting impression. These compositions were primarily based on biblical texts, reflecting his deep faith and commitment to the Lutheran church.

One of his most renowned works from this period is “Actus Tragicus.” It is a masterpiece that embodies the subtle complexities of his musical style.

While his complex musical style was not always appreciated by the church’s pastor who favored simplicity, Bach continued to innovate, pushing the boundaries of what was considered traditional church music.

Bach’s Influence on Community Music

Bach’s influence extended beyond his compositions and into the realm of community music.

  • His role in Mühlhausen was not just limited to composing.
  • He also played an active part in revitalizing the local music scene.
  • This involved engaging with the community, sharing his love for music, and encouraging others to appreciate the art form.
  • His passion for music was infectious, and his influence helped mold the musical landscape of Mühlhausen.

Bach’s Role in Rebuilding the Church Organ

Alongside his compositional work, Bach played a crucial role in rebuilding the church organ in Mühlhausen. He had a profound understanding of the instrument’s mechanics. This made him the ideal candidate for this task.

His expertise was invaluable in restoring the organ to its former glory. And in doing so, he solidified his legacy as a versatile musician who could not only compose extraordinary music but also understand and repair the instruments that produced it.


In essence, Bach’s tenure in Mühlhausen was a pivotal time in his career. He composed some of his most remarkable works, influenced the community’s music culture, and even rebuilt the church organ.

His time in Mühlhausen was indeed a testament to his creative genius and his passion for music.


4. Bach’s Tenure in Leipzig: A Flourishing Period

In 1723, Johann Sebastian Bach embarked on a significant phase of his career when he was appointed Thomaskantor, director of church music, in Leipzig.

This position required him to oversee the St. Thomas School and provide four churches with music, primarily the St. Thomas Church and the St. Nicholas Church, but also to a lesser extent the New Church and St. Peter’s Church.

In this capacity, Bach’s genius truly began to flourish as he crafted musical masterpieces for these religious institutions.

The position of Thomaskantor was considered “the leading cantorate in Protestant Germany” and gave Bach an opportunity to further expand his musical prowess. But, his relationship with his employer, Leipzig’s city council, was not always smooth. Despite the professional disagreements, Bach held this prestigious post for 27 years until his death.

His Contributions during This Tenure

During his tenure in Leipzig, Bach’s contributions to cantatas were noteworthy.

  • His role as Thomaskantor entailed composing most of the pieces for the church services himself. He was not alone in this massive undertaking.
  • The older members of the St. Thomas Choir assisted him in finishing the vocal performance parts and during rehearsals. This collaborative effort resulted in a rich output of music that still resonates today.
  • One of the highlights of these middle years (1730–1739) was the composition of a Kyrie–Gloria Mass in B minor, which he later incorporated into his Mass in B minor.
  • He leveraged this work in his bid to earn the title of Court Composer from the prince, a title he eventually received. This accomplishment further solidified his reputation and increased his bargaining power with the Leipzig council.

In sum, Bach’s time in Leipzig stands as a testament to his unwavering commitment to his craft and passion for music. His prolific output, despite the challenges he faced, marks this period as a flourishing epoch in his musical journey.

It is during this time that Bach’s genius truly unfolded, leaving an indelible mark on the world of baroque music.


5. Stylistic Evolution and Influences

Johann Sebastian Bach, a name synonymous with the Baroque era’s musical brilliance, underwent a profound stylistic transformation between 1708 and 1714.

The music he composed during this period not only demonstrated his mastery of counterpoint, harmony, and motivic organization but also revealed how his exposure to international rhythms, forms, and textures shaped his musical identity.

Profound Change in Bach’s Style (1708-1714)

In the early years of the 18th century, Bach began to break away from traditional German styles. He developed a unique and innovative approach that would define him as one of the most influential composers of his time.

His capacity to blend soft and gentle melodies with complex rhythmic patterns created a distinctive Bachian geometry, devoid of harsh angles and characterized by spiraling curves.

This stylistic evolution was not only aesthetically pleasing but also exhibited Bach’s ability to push boundaries and challenge conventional musical norms.

Impact of Italian Opera and Concerto Composers

Bach’s shift in style during this period was influenced by Italian opera and the works of concerto composers like Antonio Vivaldi. These foreign influences encouraged Bach to enrich his compositions by incorporating elements from abroad into his music.

This fusion of styles allowed Bach to produce hundreds of cantatas, both sacred and secular, that were uniquely multi-dimensional, resonating with listeners from various cultural backgrounds.

The baroque mastermind’s ability to absorb and adapt different musical styles into his own compositions illuminates why he was such a trailblazer. He didn’t just make music, he transformed it.

He blend various elements into a harmonic symphony that would echo through the centuries. Bach’s stylistic evolution stands as a testament to his genius, underscoring his unparalleled contribution to the world of music.


6. Celebrated Compositions: Brandenburg Concertos and the Mass in B minor

Johann Sebastian Bach’s genius is remarkably epitomized in his most celebrated works, notably the “Brandenburg Concertos” and the “Mass in B minor“. These compositions not only showcase his versatility as a composer but also underline his profound impact on the world of music.

The Brandenburg Concertos

Written between 1708 and 1721, the “Brandenburg Concertos” is a collection of six instrumental works that stand as some of Bach’s most notable contributions to Baroque concert music.

Each concerto features a different group of soloists, creating a diverse range of moods and even structures. This was quite groundbreaking for an era when concertos were expected to follow a conventional three-movement structure: fast, slow, fast.

The Mass in B minor

The “Mass in B minor holds a special place among Bach’s compositions. It is often seen as the culmination of his life’s work.

Bach began this monumental piece in 1733 for diplomatic reasons. He completed it during the last years of his life when he had already gone blind. The mass is a synthesis of every stylistic and technical contribution Bach made to music. It is one of his most significant works.

What makes the “Mass in B minor” unique is that it is a Missa tota, a complete mass. This is unusual for a Lutheran composer like Bach, whose masses typically consisted only of Kyrie and Gloria. In fact, the mass was likely never performed in its entirety during Bach’s lifetime.

Despite these challenges, the “Mass in B minor” remains one of Bach’s most popular vocal works. Its manuscript, held by the Berlin State Library, has been included in UNESCO’s Memory of the World Register.
