The acoustic bass guitar is a bass instrument with a hollow wooden body similar to, though usually somewhat larger than, that of a 6-string acoustic guitar. Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar. It can, more rarely, be found with 5 or 6 strings, which provides a wider range of notes to be played with less movement up and down the neck.

In the following year, Juan Bermudo wrote in his Declaracion de Instrumentos Musicales: 'We have seen a guitar in Spain with five courses of strings.' Bermudo later mentions in the same book that 'Guitars usually have four strings,' which implies that the five-course guitar was of comparatively recent origin, and still something of an oddity."

If you know how to play an E major chord, then you know how to play an A minor chord—just move the chord whole shape over a string. Make sure your first finger is curled, so the open first string rings clearly. Avoid playing the open sixth string when strumming the A minor chord. There are situations when it makes sense to reverse your second and third fingers when playing the A minor chord.
For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is usual to play inverted chords on the guitar when they are not part of the harmony, since the bass guitar can play the root pitch.
This month, HBO released a new documentary about Kurt Cobain's life called Montage of Heck. Unlike past documentaries on the legendary guitarist and singer, this one highlights his humanity and shares perhaps the most intimate look at his life that his fans have ever had.  Director Brett Morgan worked with Cobain's family, including his daughter Frances Bean Cobain, who provided home movies, photographs, and journals. At times funny and at other times deeply sad, Montage of Heck manages to gi

Electric guitars, introduced in the 1930s, use an amplifier and a loudspeaker that both makes the sound of the instrument loud enough for the performers and audience to hear, and, given that it produces an electric signal when played, that can electronically manipulate and shape the tone using an equalizer (e.g., bass and treble tone controls) and a huge variety of electronic effects units, the most commonly used ones being distortion (or "overdrive") and reverb. Early amplified guitars employed a hollow body, but a solid wood body was eventually found more suitable during the 1960s and 1970s, as it was less prone to unwanted acoustic feedback "howls". As with acoustic guitars, there are a number of types of electric guitars, including hollowbody guitars, archtop guitars (used in jazz guitar, blues and rockabilly) and solid-body guitars, which are widely used in rock music.
Unlike many string instruments which use a bow to create a sound, guitars are played by plucking or strumming the strings on the instrument, which vibrate to create a sound. Chords are played when the guitarist holds their fingers down on more than one individual string to change its length, which in turn changes the frequency of the vibration created - in other words, it creates a different note. Performers often use guitar tabs, rather than sheet music, when learning music: this acts as a kind of 'map' to teach guitarists where to put their fingers on the strings.
