One of the most important (and sometimes the most difficult) things to do in playing a uke is getting it in tune. If it is not in tune
it won’t really sound right. For various reasons stringed instruments constantly go out of tune, so you should always tune up
before playing. Learning how the strings should sound takes a lot of time, but don’t let that discourage you. Electronic tuners can now be
purchased very reasonably and should be considered an essential investment for any uke player.
There are a number of dedicated ukulele tuners available, and also any chromatic tuner will also do the job nicely.
The important thing about tuning your uke in standard C tuning is that the 4th string is tuned
higher than the 3rd string. The 3rd string is tuned to middle C and the 4th string is tuned to G above
middle C. Therefore the 3rd string open is the lowest note on the uke. This is referred to as “re-entrant tuning.”
