Pentatonic modal music, which has large note gaps and is commonly associated with Ethiopian music, is the most popular type of Ethiopian music. Tezeta, bati, ambassel, and anchihoy are the four primary modes of the Qenet modal system. This is the foundation of Ethiopian Highlands music. Three other modes that can be replaced for the previously stated modes are tezeta minor, bati major, and bati minor. The qenet is used in the titles of certain songs, such as tizita, a ballad about remembering. These modes’ pitches may stray greatly from the Western-tempered tuning system when played on traditional instruments, but they are tempered when played on Western instruments like pianos and guitars. Both monophonic and heterophonic works are common in highland Ethiopian music. Polyphonic music may be heard in a few southern cities. Although Majangir includes just four parts, Dorze polyphonic singing can have as many as five (edho). Traditional music is a big part of Ethiopian culture. Despite the fact that popular music is played, recorded, and listened to, the majority of artists also sing traditional melodies, which are preferred by the majority of listeners. When Haile Selassie was in power, he brought 40 Armenian orphans (Arba Lijoch) from Jerusalem to perform in Ethiopia, and they became an important part of the country’s rich musical heritage. When it arrived in Addis Ababa on September 6, 1924, this symphony became Ethiopia’s first official orchestra. The Army Band, Police Band, and Imperial Bodyguard Band were the most well-known orchestras in the last months of WWII. From the 1950s through the 1970s, popular Ethiopian artists included Mahmoud Ahmed, Alemayehu Eshete, Hirut Bekele, Ali Birra, Ayalew Mesfin, Kiros Alemayehu, Muluken Melesse, and Tilahun Gessesse, while popular folk musicians included Alemu Aga, Kassa Tessema, Ketema Makonnen, and Asnaketch Worku. Mulatu Astatke, a pioneer of Ethio-jazz, had a long and illustrious career. Amha Records, Kaifa Records, and Philips-Ethiopia were the three most important Ethiopian record companies at the period. Since 1997, Buda Musique’s Éthiopiques series has republished some of these songs and albums on compact disc.
