- The chief difference in the evolution of orchestral instruments in Ill Bethisad is the continued development of the keyed brass instruments as a separate and parallel subfamily (alongside the piston instruments). Thus, avid listeners of classical music *there* have long known and appreciated the different tonal qualities of ophicleide and euphonium, and have come to expect them where composers, such as Verdi and Wagner, have given voice to them. Both families of brass instruments have continued to evolve apace: the valved brass are largely where they are *here*, while the keyed brass have enjoyed continued improvements to key placement, standardised number of keys and systematisation of keywork that such instruments have not enjoyed *here*. The dichotomy of tonal colours has thus produced a modern orchestra with a slighty larger brass section than *here*'s orchestra: three piston trumpets (or cornets), two keyed trumpets (or cornets), five french horns, three trombones, one or two euphoniums, one or two ophicleides, one tuba.
- Britain is famous worldwide for its varied musical output, from fine classical composers and orchestras, to town brass bands, church orchestras and traditional bardic strains. Popular and folk music find an excellent environment to meld into new and fantastic forms. See Kemr, keyword "Music".
- NAL to the FK. This kind of singing, called solfey, or solfeġ as it's called in Brithenig, derives from 15th and 16th century styles which travelled to the Americas with the early settlers. As is still commonly heard in British churches, particularly in England, solfey singing is often accompanied in the bass part by a brace of serpents or ophicleides. The English, who have recently rediscovered this curious and ancient British passtime of comunal singing, have taken to calling it gallery music.
- A new Americo-British music that evolved in the early to mid 20th century is Fuzió: a "fusion" of Zaydeco, Jass and traditional British/Celtic.
- Qvelbe music has become popular throughout the Scandinavian Realm, particularly in the West Indies and in Guinea.
- Turbofolk is a style unique to the Balkans.
- Popular in all northern cities of the NAL from the late 1800's to the early 20th century was Ragtime, which is considered by some a fusion of African-American styles and European Classical music. It's most famous contributor was Scott Joplin who composed some of the most popular songs.
- Nu jass is a curious fusion of jass, ska/rocksteady, and the avant-garde, which has recently become popularised by such popular artists as Jij-Zet and Kenny North.
- Other trends are Contrey, typical of northern Louisianne, east Tejas and the western and southern provinces of the NAL; and Estompier, which evolved from the Jass movement and is a popular sort of swing dance style known for energetic moves.
Of course, there is also Classical Music:
- J. S. Bach's Premarian Concertos1; many works for fortepiano and organ - toccatas, preludes, fugues [18th cen].
- Georg Friedrich Kremer dedicated his masterpiece Die Musikalische Gabe (a.k.a. "the Forty-Eight") to his close friend J. S. Bach, who was born in the very same year as Kremer himself.
- Andrew Corelli's Concerto for Six Oliphaunts and Three Ophicleides vs. Orchestra .
- Frydryk Frączyszek Chopin, Veneda's greatest and most prolific composer, whose musical style became radically avant-gardist after 1880.
- Ravi and Anoushka Shankar have brought Indian classical music into the western conscience [c.2000].
 Although the proper German title is Preimerische Konzerte, the usual English title is, in fact Pommeranian Concertos. English is a weird language and often refuses to play by the rules. "Premarian Concertos" is a common title form found in European discographies, and is increasingly favoured by anglophone musicologists.
