Solresol

About Solresol

Solresol was created by French musician François Sudre beginning in 1827 and published in full in 1866. It is built entirely from the seven musical notes of the solfège scale (do, re, mi, fa, sol, la, si), making it uniquely multimodal — it can be communicated through speech, singing, musical instruments, hand gestures, colors, or numbers. Words are composed of one to five syllables, with related concepts sharing common roots. Solresol was the first artificial language to gain widespread interest and was praised by Victor Hugo and Napoleon III. It remains one of the most creative approaches to language construction ever devised.
