Bluegrass music is an offshoot of the country and western musical genre. As with country music, bluegrass has its foundation in the music of Ireland, Scotland and England. If bluegrass is centered on one area of the USA, it is Appalachia. The people are of Irish and Scottish descent and in their music instrumental virtuosity is not a poor relation of singing. In most forms of popular music the instruments back up the vocalist, but in bluegrass the vocals and the instruments are all just members of the team. In a bluegrass band everybody is expected to take a solo just as they do in a jazz band. The instruments associated with bluegrass music are acoustic guitar, banjo, fiddle and bass. The main thing to remember if you want to learn to play bluegrass scales is to learn some t easy guitar songs unes. That is what music is made of. The scales are just the foundation of melodies and you need to be able to break out of the confinement of your scale as soon as possible. The other thing learning tunes is good for is developing right hand speed. As you can tell from listening to bluegrass music, speed flatpicking is essential. If you are interested in learning bluegrass music and you would like to start by learning scales, start with the major scales in the open position. Do not bother with going up the neck of the guitar yet because learning your scales in the open position is crucial for playing bluegrass solos. Learn the scale in the key of G first, then C, D, F, A and E. Learn the keys one at a time so that you are comfortable with one before you go onto the next key.
