In the field of musicology and ethnomusicology tradition refers to the belief systems, repertoire, techniques, style and culture that is passed down through subsequent generations. Tradition in music suggests a historical context with which one can perceive distinguishable patterns. Along with a sense of history, traditions have a fluidity that cause them to evolve and adapt over time. While both musicology and ethnomusicology are defined by being 'the scholarly study of music'  they differ in their methodology and subject of research. 'Tradition, or traditions, can be presented as a context in which to study the work of a specific composer or as a part of a wide-ranging historical perspective.' 
Samhain was a fire festival. Sacred bonfires were lit on the tops of hills in honor of the Gods. The townspeople would take an ember from the bonfire to their home and re-light the fire in their family hearth. The ember would usually be carried in a holder - often a turnip or gourd. They felt nervous about walking home in the dark; they were afraid of evil spirits. So they dressed up in costumes and carved scary faces in their ember holders. They hoped that the spirits would be frightened and not bother them. Children continue to dress up today in various costumes. Pumpkins are now the objects of choice into which to carve faces.
 The Adhaan begins with the declaration of the fact that God is the biggest and the highest authority and, therefore, deserves our submission and obedience the most. After this, a declaration of the oneness of God and the prophethood of Mohammed (peace be upon him) is made, which is followed by a call to God's worship - in the style taught by the Prophet (peace be upon him) - which guarantees eternal success. In the end, once again the declaration of God's incomparable greatness and His oneness is repeated to symbolize the all-encompassing nature of the belief of Tawheed (oneness of God) in Islam.
