Every guitar player suffers from tuning problems from time to time – it’s a natural part of playing a stringed instrument.
Tuning problems are particularly common in cheaper instruments, and even more expensive ones can be difficult to keep in tune in they’re not maintained well. Constantly having to retune your guitar can be very frustrating!
Guitar is an easy instrument to learn (violin is voted as the most difficult). But still guitar is a versatile instrument. It’s history can be traced to over 4000 years back. The modern acoustic guitar which we can see the way it is today got its shape around 1900s.
Modes are scales that allow you to improvise over different types of chords. They are particularly useful to improvise over chord progressions that include chromatic chords (i.e. chords that do not belong to the key of the progression). You create a set of modes by starting a scale on a note other than the root and then continue to ascend for an octave.
