Hi Robert,
Where are the steps and half steps in the major scale?
I mean, why is the half step between the 3rd and 4th notes (E and F) and not between 4th and 5th, or 5ht and 6th…?

Ricardo,
This is a great question. In fact, centuries ago the half steps were found in different places. These were called modes. Basically, if you start a scale on different notes, the half-steps will occur in different places. Think of playing the white keys starting on D and ending on D instead of going from C to C. Instead of having half-steps between the 3rd-4th and 7th-8th notes, as in a major scale, they would be between the 2nd-3rd and 6th-7th notes creating what is called the Dorian mode. You can start modes on any scale degree creating different modes.
Eventually, the major/minor tonality caught on. One reason for this is the power of the raised 7th. While the minor scale is actually a version of the Aeolian mode (which are the notes starting on the 6th note of the major scale) it is most often found in 2 altered forms, the harmonic minor (which has a raised 7th) and the melodic minor (which has a raised 6th and 7th). What is so powerful about major/minor tonality is that some tones are stronger than others. There are active tones which must resolve to restive tones. Just try playing a slow major scale ascending and stop on the 7th note. You will feel incredibly compelled to play the last note. That is the power of tonality!
Hi Robert;
I have a 7 foot Steinway piano. During these terribly cold months, it has been going out of tune.
I have a damp chaser. Would a microfiber blanket be safe to cover the INSIDE of the piano?
Also, what temperature should my gas heater be kept at night?
please let me know. I read your e-mails; they are very helpful.
Thanks,
Mary
Mary,
Your piano will keep its tuning best in a stable environment. The rule of thumb is if the piano is sitting in a place you would be comfortable sitting day and night, your piano will probably be fine. A string covering blanket could be helpful. However, the underside of the soundboard will still be exposed. Fluctuations of temperature from the 60’s to 70’s shouldn’t present problems. Avoid direct sunlight on the soundboard. This can change the tuning rapidly.
