This work is likely not in the public domain in the US (due to first publication with the required notice after 1925, plus renewal or "restoration" under the GATT/TRIPS amendments), nor in the EU and those countries where the copyright term is life+70 years. However, it is public domain in Canada (where IMSLP is hosted) and in other countries (China, Hong Kong, New Zealand) where the copyright term is life+50 years.
