Acoustic music comprises music that solely or primarily uses instrumentswhich produce sound through entirely acoustic means, as opposed toelectric or electronic means. Performers of acoustic music often increase thevolume of their output using electronic amplifiers. However, theseamplification devices remain separate from the amplified instrument andreproduce its natural sound accurately, allowing the artist to be more naturalwith the flow of the song. A microphone is placed in front of an acousticinstrument which is then wired up to an amplifier, which has a low basstherefore you can still hear the song clearly .Indie Rock music is a genre which is your own, which you have created tosuit your self. However it also means it’s a genre of alternative rock thatoriginated in the United Kingdom and the United States in the 1980s. Indierock is extremely diverse, with sub-genres that include indie pop, grunge,jangle pop, C86, and lo-fi, among others. Originally used to describe recordlabels, the term became associated with the music they produced and wasinitially used interchangeably with alternative rock.I think some indie and acoustic tend to relaxing and are a meditation in a way,because the artist tends to have a voice which stands out and sounds differentinan abstract way. These are shown by the music artists Ed Sheeran, JeremyPassion and Indie music would be Florence & The machine as she is part of anEnglish indie rock band. Indie music now-a-day is more relaxing instead of aheavy base to it.
