Hard rock is strongly influenced by blues music; the most frequently used scale in hard rock is 
the pentatonic, which is a typical blues scale. Departing from earlier acoustic based blues, hard rock makes use of more modern instruments such as electric guitars, drums and electric bass. A notable departure from traditional blues forms is that hard rock is seldom restricted to the I, IV, and V chords prevalent in twelve or sixteen bar blues, but includes other chords, typically major chords rooted on tones of the minor scale.

Among them some are AC/DC, Aerosmith, Audioslave, Bad company, Bon jovi, Deep Purple, Guns N' Roses, Nickelback, Union and so on...
Soft rock emerged in the early 1970s, both as a reaction against the increasingly heavy music (heavy metal, punk rock) that was developing at the time, and also as a reflection of the changing priorities of the Baby Boom generation.[citation needed] What set 1970s soft rock apart from its 1960s counterpart, which is usually just called "pop", is that in the 1960s' pop artists usually were vocalists who were stylistic throwbacks to the pre-rock era.
Rock music is a genre of popular music that entered the mainstream in the 1960s. It has its roots in 1940s and 1950s rock and roll, rhythm and blues, country music and also drew on folk music, jazz and classical music.
In the late 1960s and early 1970s, rock music developed different subgenres. When it was blended with folk music it created folk rock, with blues to create blues-rock and with jazz, to create jazz-rock fusion. In the 1970s, rock incorporated influences from soul, funk, and Latin music. Also in the 1970s, rock developed a number of subgenres, such as soft rock, glam rock, heavy metal, hard rock, progressive rock, and punk rock. Rock subgenres that emerged in the 1980s included new wave, hardcore punk and alternative rock. In the 1990s, rock subgenres included grunge, Britpop, indie rock, and nu metal.
A group of musicians specializing in rock music is called a rock band or rock group. Many rock groups consist of an electric guitarist, lead singer, bass guitarist, and a drummer, forming a quartet. Some groups omit one or more of these roles or utilize a lead singer who plays an instrument while singing, sometimes forming a trio or duo; others include additional musicians such as one or two rhythm guitarists or a keyboardist. More rarely, groups also utilize stringed instruments such as violins or cellos, woodwind instruments such as saxophones, and brass instruments such as trumpets or trombones.
Learning how to read music is like learning how to read and write. There are some basic rules to learning music. The basic format for a piece of music contains 5 lines and a treble clef. These are the fundamentals for anyone who wants to learn to read music. First you must learn to identify the type of clef that is present in the music piece. There are varieties of clef types, including the bass clef. You could usually think of the treble clef as the basic ‘right-hand’ on the piano, and the bass clef the ‘left-hand’. However, music notes are universal and therefore this rule cannot apply for every instrument and there are other clefs which have different rules. Don’t be put off by this, learning the notes on the treble clef and bass clef is enough to have you playing excellent sounding music.
The notes are read by their corresponding positions between or on the lines. For the treble clef, the notes on the line, listed in order from bottom to top are E, G, B, D, F. These can be remembered using a variety of quirky phrases, on such one being Every Good Boy Does Fine. The notes in between these lines correspond with the letters F, A, C, E and can obviously be remembered by the word FACE.
The bass clef is slightly different from the treble clef, since the notes on and in between the lines have different letters. The ones played on the lines include, from order of bottom to top, G, B, D, F, A. Phrases can also help in remembering this, but it’s best if you can memorise the notes or even make up one yourself, because this will enable you to memorize the notes faster. The notes in between the lines are A, C, E, G. By remembering the basic treble and bass clef notes, you will have established a foundation to reading music. Each letter has a note assigned to it on a particular instrument, and if they are the same then the sound made by any instrument will have the same sound. Therefore, if you learn to read music for one instrument, the entire process for learning another becomes much easier.
Is there more to reading music than just these two? Yes there is, there is so much to learn you cannot possibly hope to understand it all overnight. It all comes down to how far you want to take your reading ability. The best at reading music are able to read the notes just like a book, taking a quick look before actually playing the notes. Reading music is just like playing music – it is an art, and has to be mastered.
That's music to my ear is a common phrase used to express a person's emotional response to how a particular tune can make them feel. Some people listen to music all the time. Some study the art of playing an instrument. It's therapeutic; it's enriching; it's a way of creating moods in any environmental setting. If you are interested in music for more than the pure enjoyment people get out of listening to it, then learning about music theory is an ideal mode for you.
Music theory allows you to voice your opinion with others in the field, expand your musical horizon. Give a little input to a fellow musician and you'll get something in return.
Chord progression and harmony, two features of music theory, help broaden any musician, regardless of their genre of study. Chord progression is a series of chords that are used to harmonize music. All compositions use chord progression. Those that improvise - which, as already mentioned, adds charm and magic to the environment of music - invent brand new melodies that blend in with an existing chord. It's a musical transition, something that must be practiced, repeatedly. The great composers and musicians develop chord progressions and transitions until it becomes natural, a second-natured maneuver.
The study of music theory will show musicians and musical scholars that the objective, initially, is not to consider an entire composition in one sitting. Instead, musicians, students and teachers alike, view a chord progression in segments, or units. These units correspond to musical sections known as stanzas.
Music nowadays seems to be one of the most popular hobbies that the youngsters are indulging in. For some, it may be just a pure form of entertainment or a way of living, whereas for the others, it can be a serious escape from their stressful lives. They use music as a medium of conveying their suppressed emotions. Not too surprisingly, it makes them really into music.
Before, people, specially the youth, viewed Music, a subject in their primary and secondary schooling, as a conservative and boring one. With lots of different bits and pieces that should be memorized and understood without knowing their use and purpose, music then had been a vague and dull form of school activity to do.
Many are aware that music centers began to spring suddenly nowadays. People look for formal lessons and their aim is, of course, to learn music. They also want to develop the talents they believe they are blessed with.
However, with the kinds of trends, technology and methods that we have right now, music teaching has become less complicated. Indeed, different resources and tools are made readily available to be an aid to anyone who has interests in music teaching. It may be through various means like seeking the help and guidance of music enthusiasts and experts, enrolling in various learning centers, reading music-related books, availing advanced music gadgets, or browsing the web.
