A network for historic guitars and vihuelas
Hello, folks, this is more of a practical topic rather than an academic one:
When I purchased my first period instrument (renaissance guitar in my case), one of the initial problems to encounter was what tuner I should or could use. I know that A=415 and 392 are almost G# and G in A=440 respectively, so a most ubiquitous tuning fork of A=440 can be used for these pitches in a pinch. Luckily I managed to find the tuning forks of A=415 and 392Hz, but what should I do with, say, A=380?
Here I found a nice solution: this software called "Freqtune" for iPhone/iPad/iPod Touch. The great thing about this smart sftware is that you can set six different frequencies at your will. All you have to do is to set the frequency in each column on the right using the keyboard that appears when you tap the column. Then you tap one of the buttons on the left for each frequency and you have the sound of either sine, square, triangle or sawtooth wave. Obviously, the sine wave is the most preferable for the purpose. Freqtune costs 350 JPY which is way cheaper than any tuning fork(s) so long as you already have either of the hardware mentioned above. The software was developed by a Japanese company but the language on which it is based is English. It should be sold internationally.
