I am in South Africa with my girlfriend. We have been traveling around the world for 5 months and have another few moths left. We are thinking to take the next two months, buy / rent a truck and drive up from south africa, through Namibia, Botswana, Zimbabwe, Mozambique and then to Tanzania.
The Standard C tuning (sometimes referred to as Re-entrant tuning) is the most common ukulele tuning for soprano, concert and tenor ukes.
Where I live, standard tuning is $90.00, give or take. In LA, I have heard that $150.00 is the going rate. Also, a piano that is badly out of tune (hasn't been tuned for at least 5 years) will cost more to tune because it needs what's known as a pitch raise. This entails multiple passes across the keyboard, since bringing it up all at once stresses the piano and makes the tuning unstable.
