Abstract: This study was conducted to identify, record, notate and compile the original tunes of the ‘Pasyon’, which was part of Philippine tradition and cultural heritage. It aimed to preserve and promote the century-old passion tunes so that the next generation will continue to treasure it. It dealt on the identification, gathering and notation of holy week passion tunes in the town of Santa Maria, Bulacan, Central Luzon, Philippines. The respondents in this study included old folks who frequently join in the Pabasa ng Pasyon during holy week. The population was composed of fifty (50) old folks of the town, whose ages range from 60-100 years old. The study was conducted in March of 2019. Interviewing of old folks and recording of holy week passion tunes were used as procedures in gathering data in this study. These century-old passion tunes were notated and used by local band musicians in accompanying Passion chanters.
