In 1903, the family moved to Arnhem, where he attended primary school and secondary school until 1918. He was a sickly child, and was placed in a special school at the age of seven and failed the second grade. Though he excelled at drawing, his grades were generally poor. He also took carpentry and piano lessons until he was thirteen years old. In 1919, Escher attended the Haarlem School of Architecture and Decorative Arts. He briefly studied architecture, but he failed a number of subjects and switched to decorative arts.

Johann Sebastian Bach was a German composer, organist, harpsichordist, violist, and violinist of the Baroque Period. He enriched many established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad,... particularly from Italy and France. Bach wrote much music, which was revered for its intellectual depth, technical command, and artistic beauty. Many of his works are still known today, such as the Brandenburg Concertos, the Mass in B minor, the Well-Tempered Clavier, and his passions, cantatas, partitas, and organ works. Bach was born in Eisenach, Saxe-Eisenach into a very musical family; his father, Johann Ambrosius Bach was the director of the town's musicians, and all of his uncles were professional musicians. His father taught him to play violin and harpsichord, and his brother, Johann Christoph Bach taught him the clavichord, and exposed him to much contemporary music. Bach also sang, and he went to the St Michael's School in Lüneburg, because of his skill in voice.
