Louis Glass was born in 1864. His childhood home was full of music. His father, Christian Henrik Glass, was a prominent and highly recognised music educator whose primary instrument was the piano, though he was also an organist. In 1877, he founded his own music conservatory, which focused on piano playing and soon gained a good reputation. The piano works of Louis Glass make up a significant part of his collected works. Aside from arrangements of orchestral works in different piano editions, the many two-handed piano pieces appear as either single movements or as part of collections. The collections of piano works include no fewer than 12 opus numbers with a total of 75 movements from Glass’s entire output.
