The IOHIO's Twelve International Organ and Early Music Festival will take place in the second half of February, 2018.







The outstanding collection of seventy-two baroque pipe organs is one of Oaxaca´s lesser-known cultural treasures. Built between 1686 and 1891, these organs remain today as evidence of a glorious musical past when Oaxaca was the third most important center of music in New Spain, after Mexico City and Puebla, and a church was not considered complete unless it had an organ. Beginning in the 1990s, a growing awareness and appreciation of these marvelous instruments has led to conservation and restoration projects, concerts, and festivals throughout the state.

Although many hundreds of organs have existed in Oaxaca since 1544 (the earliest archival reference to an organ), over the course of time most of them have been lost due to normal deterioration, natural disasters, neglect, and/or willful destruction. Nine organs have been restored, reconstructed, or repaired and are now playable, while the remaining sixty-three instruments exist in varying states of conservation. Some are represented only by an empty exterior case or some interior parts, while others are completely intact and may be restored someday. But despite their condition, the relatively small sample of seventy-one organs is enough to reveal a fascinating panorama of construction techniques and musical characteristics spanning over two hundred years. Furthermore, it is almost certain that there are still more organs in Oaxacan villages waiting to be discovered, and it is urgent to register them before they disappear.


                                OF THE OAXACAN ORGANS                                 

  • The Oaxacan organs preserve elements of Iberian baroque organ design—one 45-note keyboard with a short octave (until the mid-19th century), no pedals, and meantone temperament—at the same time that they developed idiosyncratic exterior features—a profile with rounded protuberances on the sides (“hips”) and the unusually lavish case and pipe decoration of many 18th-century instruments.
  • Most of the organs are still in relatively authentic condition and have been little altered or modernized over the course of time. This is in large part related to the isolation and poverty of many of the communities in which they are located, the abandonment and neglect of the organs once they ceased to function, and a conservative tradition of organbuilding resistant to change.
  • Around 40% of the Oaxacan organs date from the 18th century or earlier, whereas most of the organs in other states of Mexico date from the 19th century.
  • Most of the organs were built in the state of Oaxaca, with the exception of a few later examples originating in Puebla. Although projects were sometimes supervised by non-Oaxacan maestros, the actual construction and decoration of the organs would have been carried out by local artisans, manifesting the same talent for fine craftsmanship which still flourishes in the state today.
  • All the Oaxacan organs are still located in churches, not one of them is in a museum.



Founded in the year 2000 with the support of the Alfredo Harp Helú Foundation, the Instituto de Órganos Históricos de Oaxaca A.C. (Institute of Oaxacan Historic Organs or IOHIO, pronounced YOYO) strives to raise awareness about the organs by means of the following activities:


  • Assure that the restored instruments are played and maintained and that the unrestored instruments are protected, conserved, and documented
  • Offer musical and technical training at the local level.
  • Promote the organs through concerts, festivals, publications, conferences and recordings 
  • Increase knowledge about the organs through archive and community research



The IOHIO is committed to protect, conserve, document, and promote the historic pipe organs in the state of Oaxaca, Mexico; to raise consciousness about their importance as part of the national and international cultural heritage; and to reintegrate the restored instruments into the present-day life of their communities.



We believe that the historic pipe organs merit respect and support. These multifaceted instruments still delight us with their rich sound, their elegant appearance, and their fine mechanism. In addition, they represent a link to the history of their communities and remind us of the commitment of the ancestors of present-day Oaxacans who financed their construction.
