Evidently, we argue the existence of a Christian god with logic and it can be proven.
Then a 'grammar expert' finds bad grammar in this sentence.
"I guess it's like grammar. Though people with bad grammar look or sound stupid. Oops, it's the same!"A 'grammar expert' who is still struggling to start a sentence with a capital letter and end it with a full stop. A guy who uses the verb 'practise' as a noun. This guy also says that playing the violin in tune is not important. Not necessary.
Then tempering in music is mentioned. Statements like this occur, "I'm settled down in my arm chair with a coffee. Tempering?" Is he cooling the coffee or playing with his own dick?
Okay, hold your temper, what is tempering?
Here's a simple introduction to tempering.
Look at the piano keyboard.
There are 12 different notes that repeat in higher and lower octaves, but there are only 12 different sounds.
The white notes are called A B C D E F G. The black notes are called A# or Bb C# or Db D# or Eb F# or Gb G# or Ab.
Why do the black notes have two names?
There is nothing in nature that makes these 12 notes fit together in perfect tune. Many cultures found that you could get five notes pretty well in tune but, after that, it got a bit tricky. Well before the Europeans, the Chinese worked out how to add 'in tune' notes to these original five, but they decided that they liked those original five, on their own, better. To this day, like many other cultures, traditional Chinese music uses the pentatonic scale - C D E G A. Blues and rock guitarists liked this sound too. You'll hear it in a lot of rock music. Blues guitarists like to add one more note.
Sometime, in the 1700s, they were struggling with pianos because a lot of the keys (there are 12 major keys) sounded awful (read 'out of tune'). They decided to slightly shift all the notes so that the distances between them were all even. This gave all the keys the same sound. In this process A# and Bb, for example, were shifted so that they became the same note.
Remember that there is a lot more detail to tempering and I'm just trying to tell you the basics.
The two well known tempered instruments are the keyboard and the guitar. Most other instruments, like the violin, the oboe, the clarinet and the trumpet, just 'play into this system'. For example, on the violin, there are no frets and any note is possible. Hey, but if a violinist plays outside of this system, when playing with a pianoforte, it is going to sound 'wrong'. Define wrong? Well, it'll sound weird to most ears.
A man named Johann Sebastian Bach wrote a famous work called The Well Tempered Clavier.* This consists of two sets of preludes and fugues in all 24 major and minor keys for keyboard.
This guy obviously liked tempering.

There you go. If you leave a silly comment, I'll tell you so.
And don't play with yourself while drinking coffee. You might spill hot coffee onto it.
Ciao tutti.

Does this mean that when I'm playing with my Richard (you), on violins, the notes we play that sound fine to us, won't necessarily agree with mother's piano if we were to stop and check?
Your mother would have said to you - "I hope that you washed your hands Robert, before playing on my piano after playing with yourself."
I'm very tempted to go with TC's answer, but you seem to have missed the point Rob. Mozart's music is in the tempered style, just like the music of 'Levin' Helm and his band with that hot drummer Palmerston North. To hear untempered music, you'll probably have to listen to music from different cultures.

My point is that when I play a scale by ear on my cello, every note except the octave will sound slightly out of tune with a piano or guitar. The fifth and minor third will be slightly flat and the fourth and major third slightly sharp on the piano etc. So who is really in tune? If I stop and bang a fifth on mother's piano I am tempted to adjust my finger to match it, but I am really being deceived, and Richard might say unjustly "Rob you are out of tune, it doesn't match the two to the square root of twelve even tempering steps".
"Rob you are out of tune, it doesn't match the two to the square root of twelve even tempering steps". I would never say something stupid like that. However, you would be doing yourself a huge favour to get all those cello notes in tune with a piano. I think that you have made your mind up to miss the point of what I have said.

Yes you are perfectly correct. Equal tempering is based on the steps using the formula twelve to the square root of two! The reason it was decided in the mid eighteenth century to. do this was that it allowed transposition. Nevertheless it is an approximation, and other types of tempering are still in use and allow pure sounding tones and less harmonic clashes especially in chords. Because non fretted instruments like our cellos and violins allow infinite notes I still stand by my statement that a perfectly in tune scale, for instance, is only truly possible on these. It's a fascinating subject, the physics and mathematics of which are very complex.
Just a foot note. A video I watched said that that Bach didn't write the Well Tempered Clavier for equal tempering. There were several methods of tempering in use at that time. (And I'm not implying you said he did)..
Can you elaborate on different accidental names for the one note being in fact different sounding (Ab and G#). None of the videos I watched mentioned this apart from showing an old piano with more than the normal number of black keys
"You're becoming a bit of a bore, Robert." Gloria.
Look, they evidently had slightly different pitches. Playing in tune is about listening to other instruments that are also playing and listening to what you are playing. Warm up with scales and arpeggios and listen. Listen, listen, listen.
I've done two hours of violin practice so far today.
